24- and 26-membered macrocyclic diorganotin(IV) bis-dithiocarbamate complexes with N,N?-disubstituted 1,3- and 1,4-bis(aminomethyl)benzene and 1,1?-bis(aminomethyl)ferrocene as spacer groups

The potassium bis-dithiocarbamate (bis-dtc) salts of 1,3- bis(benzylaminomethyl)benzene (1,3-Bn-ambdtc), 1,3-bis(iso-butylaminomethyl) benzene (1,3-iBu-ambdtc), 1,4-bis(benzylaminomethyl)benzene (1,4-Bn-ambdtc), and 1,4-bis(iso-butylaminomethyl)benzene (1,4- iBu-ambdtc) were reacted with three different diorganotin dichlorides (R2SnCl2 with R = Me, nBu, and Ph) in 1:1 stoichiometric ratios to give the corresponding diorganotin bis- dithiocarbamates. Additionally, the dimethyltin bis-dithiocarbamate of 1,1?-bis(benzylaminomethyl)ferrocene (1,1?-Bn-amfdtc) was prepared. The resulting complexes have been characterized as far as possible by elemental analysis, FAB+ mass spectrometry, IR and NMR (1H, 13C, and 119Sn) spectroscopy, and single-crystal X-ray diffraction, showing that the tin complexes are dinuclear 24- and 26-membered macrocyclic species of composition [{R2Sn(bis-dtc)}2]. As shown by 119Sn NMR spectroscopy, the tin centers are hexa-coordinated in all cases; however, two different coordination environments are possible, as detected by single-crystal X-ray diffraction. In the dimethyltin derivatives of 1,3-Bn-ambdtc, 1,3-iBu-ambdtc, 1,4-Bn-ambdtc, and 1,1?-Bn-amfdtc and the di-n-butyltin derivative of 1,3- iBu-ambdtc, the metal atoms are embedded in skewed-trapezoidal- bipyramidal coordination polyhedra with asymmetrically coordinating trans-oriented dtc groups. In contrast, in the diphenyltin derivative 1,3- iBu-ambdtc, the metal centers have distorted octahedral coordination with symmetrically coordinating cis-oriented dtc functions. Thus, for the complexes derived from 1,3-Bn/iBu-ambdtc, two different macrocyclic structures were observed. In the dimethyl- and di-n-butyltin derivatives, the bridging bis-dtc ligands adopt U-shaped conformations, while in the case of the diphenyltin derivative, the conformation is L-shaped. Furthermore, two different macrocyclic ring conformations can occurr, which differ in the spatial orientation of the substituents attached to the nitrogen atoms (Bn or iBu). The dimethyltin derivatives of 1,4-Bn-ambdtc and 1,1?-Bn-amfdtc have cavities, in which aromatic rings are accomodated in the solid state.

IR spectral and X-ray single crystal study of hydrogen bonds and structure of nonamethylferrocenyl- and ferrocenylcarbinols in the solid state

The influence of different substituents in the Cp-ring and at the carbinol C atm on the character and stability of H bonds in crystals of FcCHROH and 9FcCHROH, Fc = C5H5FeC5H4; 9Fc = C5Me5FeC5Me4, (R = H, CH3, C6H5, C6F5) was studied by IR spectroscopy specifically in the nu(OH) region.In the crystals, molecules associate predominantly via intermolecular OH…O bonds.However, in some of the 9FcCHROH complexes, the intermolecular O-H…?(Cp) H bonds are also formed.The major type of self-association in compounds with R = Mes is OH…?(Mes) H-bonding.It was found from the X-ray structural data for the 9FcCHMesOH that the Mes plane is almost perpendicular to each Cp ring plane.No intermolecular OH…O bonds are formed because of intramolecular shielding of the OH group.The stability of the intermolecular hydrogen bonds is determined by steric rather than electronic factors, the most stable intermolecular hydrogen bonds being formed in the case of primary carbinols.

Metathetical reactions of Re(VII) alkylidene-alkylidyne complexes of the type Re(CR?)(CHR?)[OCMe(CF3)2]2 (R? = CMe3 or CMe2Ph) with terminal and internal olefins

1-Decent and methyl 9-decenoate react with syn- and anti-Re(C-t-Bu)(CH-t-Bu)(ORF6) to give syn- and anti-Re(C-t-Bu)[CH(CH2)7Me](ORF6)2 and syn- and anti-Re(C-t-Bu)[CH(CH2)7CO2Me](OR F6)2, respectively (ORF6 = OCMe(CF3)2). The new alkylidene complexes are unstable in the presence of excess terminal olefin and decompose upon attempted isolation. However, vinylferrocene reacts relatively smoothly and reversibly with syn-Re(C-t-Bu)(CH-t-Bu)(ORF6)2 in a noncoordinating solvent to yield tert-butylethylene and primarily anti-Re(C-t-Bu)(CHFc)(ORF6)2 (Fc = ferrocenyl). anti-Re(C-t-Bu)(CHFc)(ORF6)2 (a = 9.769 (2) A, b = 30.746 (7) A, c = 10.140 (2) A, beta = 116.78 (1), V = 2719 (2) A3, space group = P21/a, Z = 4, FW = 815.50, p(calcd) = 1.992 g/cm3, R = 0.052, Rw = 0.050) was shown to be a pseudotetrahedral species with an unusually acute Re=Calpha – Cbeta angle (114.8 (7)) and short Re=C bond (1.70 (1) A). In the presence of THF or dimethoxyethane, complexes of the type syn- or anti-Re(C-t-Bu)(CHR)(ORF6)2S2 (R = Me, Et, Ph; S = THF or 0.5DME) could be prepared in high yield from Re(C-t-Bu)(CH-t-Bu)(ORF6)2 and CH2=CHR. Heteroatom-substituted (O, S, or N) terminal olefins react more rapidly than ordinary olefins with Re(C-t-Bu)(CH-t-Bu)(ORF6)2 in the presence of THF to yield complexes of the type syn- or anti-Re(C-t-Bu)(CHX)(ORF6)2(THF)2 (X = OR, SR, NR2, or p-dimethylaminophenyl). The X-ray structure of syn-Re(C-t-Bu)(CHOEt)(ORF6)2(THF)2 (a = 10.318 (1) A, b = 18.303 (2) A, c = 16.181 (2) A, beta = 96.98 (2), V = 3033 (1) A3, space group = P21/c, Z = 4, FW = 819.74, rho(calcd) = 1.795 g/cm3, R = 0.052, Rw = 0.050) showed it to be a pseudooctahedral complex containing cis alkylidyne and alkylidene ligands and a THF ligand trans to each. The Re-O bond to the THF trans to the neopentylidyne ligand is significantly longer than that trans to the ethoxymethylene ligand; presumably it is the THF ligand trans to the neopentylidyne ligand that exchanges more rapidly with free THF in solution. 2-Pentene or methyl oleate is metathesized in the presence of Re(C-t-Bu)(CH-t-Bu)(ORF6)2, and intermediate alkyidene complexes can be observed in each case. Addition of 3-hexene to Re(C-t-Bu)(CH-t-Bu)(ORF6)2 followed by TMEDA yields Re(C-t-Bu)(CHEt)(ORF6)2(TMEDA). Internal olefins are metathesized only very slowly by Re(C-t-Bu)(CH-t-Bu)(ORF6)2 in the presence of several equivalents of THF or DME or especially in neat THF or DME.

Electrochemical monitoring of reactive oxygen/nitrogen species and redox balance in living cells

Levels of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in cells and cell redox balance are of great interest in live cells as they are correlated to several pathological and physiological conditions of living cells. ROS and RNS detection is limited due to their spatially restricted abundance: they are usually located in sub-cellular areas (e.g., in specific organelles) at low concentration. In this work, we will review and highlight the electrochemical approach to this bio-analytical issue. Combining electrochemical methods and miniaturization strategies, specific, highly sensitive, time, and spatially resolved measurements of cellular oxidative stress and redox balance analysis are possible. [Figure not available: see fulltext.].

Construction of multiple switchable sensors and logic gates based on carboxylated multi-walled carbon nanotubes/poly(N,N-diethylacrylamide)

In this work, binary hydrogel films based on carboxylated multi-walled carbon nanotubes/poly(N,N-diethylacrylamide) (c-MWCNTs/PDEA) were successfully polymerized and assembled on a glassy carbon (GC) electrode surface. The electroactive drug probes matrine and sophoridine in solution showed reversible thermal-, salt-, methanol-and pH-responsive switchable cyclic voltammetric (CV) behaviors at the film electrodes. The control experiments showed that the pH-responsive property of the system could be ascribed to the drug components of the solutions, whereas the thermal-, salt-and methanol-sensitive behaviors were attributed to the PDEA constituent of the films. The CV signals particularly, of matrine and sophoridine were significantly amplified by the electrocatalysis of c-MWCNTs in the films at 1.02 V and 0.91 V, respectively. Moreover, the addition of esterase, urease, ethyl butyrate, and urea to the solution also changed the pH of the system, and produced similar CV peaks as with dilution by HCl or NaOH. Based on these experiments, a 6-input/5-output logic gate system and 2-to-1 encoder were successfully constructed. The present system may lead to the development of novel types of molecular computing systems.

A novel chiral phosphino-phosphaferrocene: Its coordination behavior and application to palladium-catalyzed asymmetric allylic alkylation

The synthesis of a novel chiral phosphino-phosphaferrocene ligand is described. The ligand possesses two electronically distinctive donor moieties and behaves either as a monodentate (with a free phosphaferrocene) or a bidentate ligand depending on stoichiometry with a coordinating transition-metal center. In the palladium-catalyzed asymmetric allylic alkylation of 1,3-diphenyl-2-propenyl acetate, a clear correlation was observed between the enantioselectivity of the reaction and a Pd/phosphino-phosphaferrocene molar ratio. With a deficient amount (to the Pd) of the chiral ligand, the highest enantioselectivity (99% ee) was achieved.

Synthesis, structure, and electronic properties of extended pi-conjugated group 6 Fischer alkoxy-bis(carbene) complexes

The synthesis, structure and electronic properties of novel Group 6 Fischer alkoxy-bis(carbene) complexes are reported. The UV/Vis spectra of these species display two main absorptions at approximately 350 and 550 nm attributable to a ligand-field (LF) and metal-to-ligand charge-transfer (MLCT) transitions, respectively. The planarity of the system and the cooperative effect of both pentacarbonyl metal moieties greatly enhance the conjugation between the group at the end of the spacer and the metal carbene fragment provoking dramatic changes in the LF and MLCT absorptions. This is in contrast to related push-pull Fischer monocarbenes, where the position of the MLCT band remains mostly unaltered regardless the substituent attached to the donor fragment. In addition, the MLCT maxima can be tuned with subtle modifications of the electronic nature of the central aryl fragment in the novel A-pi-D-pi-A (A=acceptor, D=donor) systems. DFT and time-dependent (TD) DFT quantum chemical calculations at the B3LYP/def2-SVP level have also been performed to determine the minimum-energy molecular structure of this family of compounds and to analyse the nature of the vertical one-electron excitations associated to the observed UV/Vis absorptions as well as to rationalise their electrochemical behaviour. The ability of tuning up the electronic properties of the compounds studied herein may be of future use in material chemistry. Copyright

Synthesis, molecular structure and properties of a ferrocene-based difluoropyrrolo-oxaborole derivative

Reaction of 1,1?-ferrocenedicarbonyl chloride with 3-ethyl-2,4-dimethylpyrrole in DCM produced the half-way product, namely, the ferrocene bis(2-ketopyrrole) derivative 2 and not the expected bis(dipyrromethene) compound. The 2-ketopyrrole compound readily reacted with BF3¡¤Et2O to produce the bis(difluoropyrrolo)-oxaborole compound, FBF, as a red/brown solid which was characterised by X-ray crystallography. 57Fe Moessbauer spectra for 2 and FBF were consistent with low-spin iron(II) (d6) ferrocene derivatives. A cyclic voltammogram for 2 in acetonitrile revealed a reversible wave at +0.31 V vs. Fc+/Fc (ferrocene-based) and an irreversible wave at -2.38 V vs. Fc+/Fc (ketopyrrole-based). The electrochemical behaviour is severely perturbed by the chelation of the BF2 groups. Alterations to the electronic properties of 2 by formation of FBF are also evident in the absorption profiles. DFT calculations [B3PW91, 6-31G(3df)] support the observed changes in the electrochemistry findings and the Moessbauer spectroscopic data. Reaction of 1,1?-ferrocenedicarbonyl chloride with 3-ethyl-2,4-dimethylpyrrole produces the bis(ketopyrrole) compound. Chelation of BF2 to the ketopyrrole units forms the difluoropyrrolo-oxaborole.
