Metal-directed assembly of polyferrocenyl transition metal dithiocarbamate macrocyclic molecular boxes

Novel redox-active polyferrocenyl transition metal dithiocarbamate macrocyclic molecular boxes (10a-c), (11) and (12a-c) are synthesised by reaction of the respective ferrocenyl secondary amines, namely, N,N?-bis(ferrocenemethyl)-1,3-bis(aminomethyl)benzene (4), 1,1?-bis(benzylaminomethyl)ferrocene (8) and 1,1?-bis((ferrocenylmethyl)aminomethyl)ferrocene (9) with carbon disulfide, potassium hydroxide and transition metal (zinc, copper, nickel) acetate in high yields (52-82%) and characterised by spectroscopic and electrochemical techniques. The single-crystal X-ray structure of 10a shows that each zinc atom is in tetrahedral geometry, being bonded to two dithiocarbamate ligands with Zn-S distances 2.32(1)-2.44(1) A.

From ferrocenecarbonitriles to ferrocenylimines: Synthesis, structure, and reaction chemistry

From the reaction of [PtCl2(N-CMe)2] with FcC-N (1) (Fc = Fe(eta5-C5H4)(eta5-C 5H5)) complex [PtCl2(FcC-N)(N-CMe)] (2) was obtained, which on subsequent treatment with 1 gave trans-[PtCl 2(N-CFc)2] (trans-3). The latter complex and the appropriate cis isomer (cis-3) were also accessible when [PtCl2] or [PtCl2(N-CMe)2] is reacted with a 2.6-fold excess of 1. Appropriate treatment of [PtCl2(N-CMe)2] with two equivalents of 1-acetyl-1′-cyanoferrocene (4) produced trans-[PtCl 2(Fe(eta5-C5H4CN)( eta5-C5H4C(O)Me))2] (trans-5). Coordination polymer [PtCl2(Fe(eta5-C5H 4CN)2)]n (7) was obtained by combining [PtCl2(N-CPh)2] with [Fe(eta5-C 5H4CN)2] (6). However, when 7 was reacted with PPh3 for deaggregation, [PtCl2(PPh3) 2] was formed. Addition of FcC-CLi (8-Li) to trans-3 gave pentametallic trans-[Pt(C-CFc)2(NH-CnBuFc)2] (10) via trans-[Pt(C-CFc)2(N-CFc)2] (9). When trans-3 is reacted with two equivalents of nBuLi in the absence of FcC-CH (8), trans-[PtCl2(NH-CnBuFc)2] (11) was obtained, which decomposed to FcC(-NH)nBu (12), giving FcC(O)nBu (13). Electrochemical measurements of the nitrile platinum complexes show no redox separation for the oxidation of the Fc and Fe(eta5-C 5H4)2 moieties. Compared with the noncoordinated ferrocenecarbonitriles, a shift to higher potentials is observed. In contrast, for 10 four well-separated redox events (-185, -90, +460, +545 mV) were found, which could be assigned to the oxidation of the Fc units. UV-vis/NIR spectroscopy allowed to determine an IVCT absorption (numax = 6495 cm-1, epsilonmax = 270 L¡¤mol-1¡¤cm-1, Deltanu1/2 = 2270 cm-1) for 10+, classifying this mixed-valent species as a weakly coupled class II system according to Robin and Day, while no IVCT transitions were observed for 10n+ (n = 2, 3). The structures of trans-3, cis-3, 10, and FcC(O)tBu (15) in the solid state were determined by single-crystal X-ray diffraction. Although the bond distances and angles of trans-3 and cis-3 are similar, the cis isomer crystallizes as a dimer possessing Pt-Pt distances within the sum of the van der Waals radii.

Highly efficient iridium catalysts based on C2-symmetric ferrocenyl phosphinite ligands for asymmetric transfer hydrogenations of aromatic ketones

A series of chiral modular C2-symmetric ferrocenyl phosphinite ligands have been synthesized in good yields by using 1,1?-ferrocenedicarboxyaldehyde and various amino alcohols as starting materials, and applied in the iridium(III)-catalyzed asymmetric transfer hydrogenations of aromatic ketones to give the corresponding secondary alcohols with good enantioselectivities and reactivities using 2-propanol as the hydrogen source (up to 98% ee and 99% conversion). The substituents on the backbone of the ligands were found to have a significant effect on both the activity and enantiomeric excess. The structures of these complexes have been clarified by a combination of multinuclear NMR spectroscopy, IR spectroscopy, and elemental analysis.

Synthesis of controlled pi-extended conjugate nanostructures of 1,1?-ferrocene

Synthesis of the (E,E)-1,1?-ferrocene nanostructures having controlled pi-extended conjugation was satisfactory carried out starting of 1?-[2-(1,3-dioxolan)]-1-formylferrocene (1). The molecular unit (E)-1?-[2-(1,3-dioxolan)]-1-[beta-(p-iodophenyl)ethenyl]ferrocene (2), was obtained in excellent yield by treatment of 1 with p-iodobenzyl triphenylphosphonium ylid followed by Z?E isomerization, catalyzed by iodine, in quantitative yield. Compound (E)-2 was transformed in (E)-1?-{2-(1,3-dioxolan)-1-[beta-[4-(3-hydroxy-3-methyl-but-1-ynyl)-phenyl]-ethenyl}ferrocene, (E)-4, by palladium catalyzed cross-coupling with 2-methyl-but-3-yn-2-ol. (E)-4 gives (E)-1-[beta-(4-ethynylphenyl)-ethenyl]-1?-[2-(1,3-dioxolan)]ferrocene (E)-5 by powder sodium hydroxide treatment. The molecular unit (E,E)-1-{beta-[4-(beta-(1?-formylferrocenyl)-ethenyl)-phenylethynyl]-phenyl]-ethenyl}-1?-formylferrocene, (E,E)-6, was synthesized by palladium catalyzed cross-coupling between the p-iodophenyl derivative (E)-2 and their ethynyl derivative (E)-5, in good yield. The (E,E)-1,1?-(p-iodophenyl)ethenyl ferrocene, (E,E)-7, was synthesized by reaction between 1,1?-diformylferrocene and the p-iodobenzyltriphenylphosphonium ylid, as a mixture of isomers which were purely isolated. Moreover, isomerization of the Z,Z and E,Z mixture to the E,E isomer, was induced by sunlight exposure, catalyzed by iodine, in quantitative yield. The (E,E)-1,1?-[beta-(4-ethynylphenyl)-ethenyl]ferrocene, (E,E)-10, was synthesized in good yield, by palladium catalyzed cross-coupling of compound (E,E)-7 with 2-methyl-but-3-yn-2-ol, followed by powder sodium hydroxide treatment.

Nucleophilic aromatic substitution of 2-(3(5)-pyrazolyl)pyridine: A novel access to multidentate chelate ligands

1-(Nitrophenyl) functionalized 2-(3-pyrazolyl)pyridines were obtained by a nucleophilic aromatic substitution and could be reduced to the corresponding aminophenyl substituted derivatives. These compounds can be used to co-ordinate transition metal sites or for the generation of building blocks for supramolecular chemistry. The solid state structure of a 1,1?- functionalized ferrocene, which was obtained following this route, is discussed in detail.

Inhibition of cancer derived cell lines proliferation by synthesized hydroxylated stilbenes and new ferrocenyl-stilbene analogs. Comparison with resveratrol

Further advances in understanding the mechanism of action of resveratrol and its application require new analogs to identify the structural determinants for the cell proliferation inhibition potency. Therefore, we synthesized new trans-resveratrol derivatives by using the Wittig and Heck methods, thus modifying the hydroxylation and methoxylation patterns of the parent molecule. Moreover, we also synthesized new ferrocenylstilbene analogs by using an original protective group in the Wittig procedure. By performing cell proliferation assays we observed that the resveratrol derivatives show inhibition on the human colorectal tumor SW480 cell line. On the other hand, cell viability/cytotoxicity assays showed a weaker effects on the human hepatoblastoma HepG2 cell line. Importantly, the lack of effect on non-tumor cells (IEC18 intestinal epithelium cells) demonstrates the selectivity of these molecules for cancer cells. Here, we show that the numbers and positions of hydroxy and methoxy groups are crucial for the inhibition efficacy. In addition, the presence of at least one phenolic group is essential for the antitumoral activity. Moreover, in the series of ferrocenylstilbene analogs, the presence of a hidden phenolic function allows for a better solubilization in the cellular environment and significantly increases the antitumoral activity.

Second-order nonlinear polarizability of ferrocene-BODIPY donor-acceptor adducts. Quantifying charge redistribution in the excited state

A series of dyads and triads using ferrocene (Fc) as the donor and 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) as the acceptor, linked either directly or through an N-phenylmethanimine or ethynylbenzene linker have been synthesized. While the former (directly linked) dyads were prepared through acid catalyzed condensation of pyrrole with ferrocenecarboxaldehye or 1,1?-ferrocenedicarboxaldehyde followed by oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ), the latter two sets (imine and alkyne linked) of dyads were obtained through Schiff base condensation or Sonogashira coupling reactions, respectively. The compounds were fully characterized with spectroscopic data and single crystal X-ray analysis in one case. The peaks corresponding to the Fe(ii)/Fe(iii) redox couple at 0.33 to 0.38 V showed a varying degree of positive anodic shift, which reflected the strong electron withdrawing effect of the corresponding BODIPY unit. The first hyperpolarisability, beta, was measured in chloroform using the femtosecond hyper-Rayleigh scattering (HRS) method at 1300 nm. Interestingly, from the betaHRS values, the dominating role of the Fc donor and the intervening linker could be established, which correlated well with the experimental linear optical data as well as theoretical data calculated using density functional theory (DFT) and time-dependent DFT calculations. This work constitutes the first report where electron accepting power of BODIPY in combination with the Fc donor moiety, is exploited and we demonstrate that the values are comparable to that of push-pull derivatives where BODIPY was used as the conjugated linker.

Stepwise synthesis of octamethylferrocene-1,1?-dicarbaldehyde. Preparation of new electron donors for charge-transfer complexes

A stepwise synthesis of octamethylferrocene-1,1?-dicarbaldehyde (3), starting from 1,2,3,4-tetramethyl-5-(methoxycarbonyl)cyclopentadiene (7) is described, involving ferrocene formation, ester reduction to the corresponding bis(hydroxymethyl) derivative 9, and MnO2 oxidation. The aldehyde 3 readily reacts with different phosphonates derived from sulfurcontaining heterocycles in a Wittig-Horner reaction to form new electron donors that may be used in the preparation of various charge transfer complexes. The X-ray crystal structures of 1-[(1,3-benzodithiol-2-ylidene)methyl]-2,2?,3,3?,4,4?,5, 5?-octamethylferrocene (11a), 1-[(1,3-dithiolo[4,5-b][1,3]dithiol-2-ylidene)methyl]-2,2?,3,3?,4, 4?,5,5?-octamethylferrocene (11b), 1,1?-bis[(1,3-benzodithiol-2-ylidene)methyl]-2,2?,3,3?,4, 4?,5,5?-octamethylferrocene (12a), and 1,1?-bis[(5,6-dihydro-1,3-dithiolo[4,5-b][1,4]dithiol-2-ylidene)methyl]-2, 2?,3,3?,4,4?,5,5?-octamethylferrocene (12c) have been determined. In these compounds the planes of the sulfur heterocycles are oriented at angles of 60-75, with respect to the plane of the respective Cp ring.
