Highly Diastereo- and Enantioselective Synthesis of Nitrile-Substituted Cyclopropanes by Myoglobin-Mediated Carbene Transfer Catalysis

A chemobiocatalytic strategy for the highly stereoselective synthesis of nitrile-substituted cyclopropanes is reported. The present approach relies on an asymmetric olefin cyclopropanation reaction catalyzed by an engineered myoglobin in the presence of ex situ generated diazoacetonitrile within a compartmentalized reaction system. This method enabled the efficient transformation of a broad range of olefin substrates at a preparative scale with up to 99.9 % de and ee and up to 5600 turnovers. The enzymatic product could be further elaborated to afford a variety of functionalized chiral cyclopropanes. This work expands the range of synthetically valuable, abiotic transformations accessible through biocatalysis and paves the way to the practical and safe exploitation of diazoacetonitrile in biocatalytic carbene transfer reactions.

APPLICATIONS OF THE QOARTZ CRYSTAL MICROBALANCE TO ELECTROCHEMISTRY. MEASUREMENT OF ION AND SOLVENT POPULATIONS IN THIN FILMS OF POLY(VINYLFERROCENE) AS FUNCTIONS OF REDOX STATE

The quartz crsytal microbalance (QCM) technique is applied to a study of ion and solvent content within poly(vinylferrocene) (PVF) as a function of redox state in various supporting electrolytes.It is concluded that in ClO4(-) and PF6(-) containing electrolytes the oxidation of the film occurs with little and no change in solvent content of the film, respectively.These findings are in agreement with previously postulated phaselike behavior for this system.Multiple peaks are observed in the voltammetry of the PVF film in Cl(-) containing eletrolytes.Based on the concurrent QCM measurements the structure in the voltammetric response is proposed to result from the electrochemically induced dissolution or delamination of the film and a new charge transport (diffusional) situation which results from loss of the film from the surface.The QCM technique is shown to be a powerful tool for the study of process which result in mass changes at solid/liquid interfaces, especially electrode surfaces.

Structural influences on the electrochemistry of 1,10-di(hydroxyalkyl) ferrocenes. Structure of [Fe{h5-C5H4eCH(OH)e(CH2)3OH}2]

Abstract A series of 1,1′-di(hydroxyalkyl)ferrocenes, [Fc'{(CH 2)nOH}2], with n = 1 (1), 2 (2), 3 (3) and 4 (4) and Fc’ = Fe(eta5-C5H4)2, was synthesized. The electrochemistry of the di(hydroxyalkyl)ferrocenes was studied by cyclic voltammetry in CH2Cl2/0.1 M [N nBu4][PF6] utilizing a glassy carbon working electrode. The ferrocenyl group showed reversible electrochemistry with the formal reduction potential, Eo’ , inversely proportional to alkyl chain length and approximately 59 mV smaller than those of the corresponding mono(hydroxyalkyl)ferrocenes derivatives [Fc(CH2)mOH] with m = 1 (1m), 2 (2m), 3 (3m), and 4 (4m) and Fc = Fe(eta5-C 5H5)(eta5-C5H4 -). The tetraalcohol [Fc'{CH(OH)(CH2)3OH} 2], 5, possessing four OH functionalities, two in the terminal positions and two more, one on each of the two alpha-C relative to the ferrocenyl (Fc’ for dialcohols or Fc for monosubstituted derivatives) group, was isolated as a side product during the synthesis of 4. The formal reduction potential of 5 was Eo’ = -24 mV vs. FcH/FcH+ and closely approached Eo’ of [FcCH(OH)CH3] (Eo’ = -11 mV), [Fc'{CH(OH)CH3}2] (-21 mV) and 1 (0.00 mV vs. FcH/ FcH+). The single crystal X-ray structure of the tetraalcohol 5 (Z = 8, orthorhombic, space group Pbca) was also solved.

Characterization of coating systems by scanning electrochemical microscopy: Surface topology and blistering

Operation of the scanning electrochemical microscope used in feedback mode over a coated metal allows changes in the state of the coating surface to be monitored during immersion in aqueous electrolytes. This paper reports changes in the coating induced by specific anions in the electrolyte in situ during immersion. Significant surface roughening is observed for immersion times shorter than 1 day when the electrolyte contains chloride ions. This effect is also observed when the oxygen dissolved in the electrolytic phase is employed as redox mediator for SECM imaging. The coated system exposed to chloride-free electrolytes containing sulphate or nitrate maintains a featureless topography within the same time scale. The observed features are due to the nucleation and growth of blisters at the metal/coating interface induced by chloride ions in the environment. The implication is that ionic migration occurs simultaneously with the absorption of water by the coating already from the beginning of exposure to the aqueous environment. The unique role of chloride ions compared with sulphate or nitrate ions towards coating performance has been established at a very early stage following immersion of the sample.

Diiron nonacarbonyl oxidized a series of alpha-phenylcarbinols to their corresponding aldehydes and ketones.In addition, this resagent converted 4-methoxybenzyl alcohol to 4-methoxybenzyl ether, albeit in low yield.Under the same reaction conditions, oxidation was a minor with a group of alpha-ferrocenylcarbinols as ether synthesis was the major reaction with those substrates which could not dehydrate; however, stereoselective olefin synthesis predominated when elimination was possible.

The formation and reactions of some new functionally substituted derivatives of (eta5-cyclopentadienyl) dicarbonylnitrosylchromium (cynichrodene)

A reaction between cynichrodenoic acid, (eta5-C5H4COOH)Cr(CO)2NO (6) and phosphorus pentachloride produces cynichrodenoyl chloride (11) in high yield.Subsequent reaction of 11 with sodium azide affords cynichrodenoyl azide (12), which undergoes Curtius rearrangement to form cynichrodenyl isocyanate (13).Subsequent hydrolysis of isocyanate 13 in aqueous KOH solution yields aminocynichrodene (14).Azide 12 also undergoes Curtius rearrangement in the presence of benzyl alcohol to produce benzyl N-cynichrodenylcarbamate (15).Reactions of acid chloride 11 with ammonia, dimethylamine or aniline lead to the corresponding carboxamides (16-18).Amide 16 is readily dehydrated to produce cynichrodenecarbonitrile (19).Reactions of acid chloride 11 with either benzyl alcohol or hydroxymethylferrocene generate the corresponding esters (20-21), whereas treatment of a tetrahydrofuran solution of 11 with pyridine affords cynichrodenecarboxylic anhydride (22) in low yield.Reactions of acetylcynichrodene (2) with organolithium reagents, leading to both carbonyl addtion and condensation products, have been investigated.Treatment of 2 with lithium diisopropylamide in diethyl ether solution produces the self-condensation product 1,3-dicynichrodenyl-but-2-en-1-one (24).Acetyl derivative 2 and benzaldehyde also undergo Claisen-Schmidt condensation in the presence of lithium diisopropylamide to afford cinnamoylcynichrodene (27).

Efficient photodissociation of anions from benzoyl-functionalized ferrocene complexes

Spectroscopic and photochemical studies of several benzoyl-functionalized ferrocene complexes in nonaqueous solvents are reported. Bands observed above 300 nm in the electronic absorption spectrum of the unsubstituted complex, Fe(n5-C5H5)2, and assigned to ligand field transitions shift to longer wavelengths and intensify upon introduction of a benzoyl group into one or both cyclopentadienide rings. Such .behavior suggests that these transitions have acquired some charge-transfer character. Visible-light (546 nm) irradiation of l.l’-dibenzoyl-ferrocene, III, dissolved in CH3CN, CH3OH, or ethyl alpha-cyanopropionate causes ring-metal cleavage to produce the benzoylcyclopentadienide ion, C6H5C(O)C5H4-, and the corresponding half-sandwich cationic complex, Fe[(n5-C5H4)C(O)C6H 5](S)3+ (S is solvent). The disappearance quantum yield, odis, for III is 0.45 in CH3OH and 0.28 in ethyl alpha-cyanopropionate and is unaffected by the presence of dissolved O2, added H2O (10 000 ppm), or added methanesulfonic acid (30 ppm). l,l?-Dibenzoylferrocenes containing substitutents on both phenyl rings undergo photoinduced ring-metal cleavage in CH3OH with odis values very similar to that of III, while monobenzoyl-ferrocenes are appreciably less photoreactive. A mechanism that accommodates the photochemical behavior of benzoyl-functionalized ferrocene complexes is discussed. In addition, a previous suggestion concerning the role of III in the photoinitiated anionic polymerization of an alpha-cyanoacrylate monomer is reconsidered in light of the present study.

Self-assembly via (N?I) non-covalent bonds between 1,4-diiodo-tetrafluoro-benzene and a tetra-imino ferrocenophane

The tetra-imino ferrocenophane (1) was cocrystallized with 1,4-diiodo-tetrafluoro-benzene (TFDIB). In the resulting compound 2, two of the four ferrocenophane nitrogens show interactions with the iodine atoms of TFDIB leading to a polymeric structure with extended linear alternating electron donor (1) and acceptor (TFDIB) molecule chains. For the first time, imino nitrogens are involved in this type of halogen bonding. The N?I non-covalent bonds (N?I distances 2.879(5) and 2.896(5)A; N?I-C angles 171.1(2) and 178.1(2)) are the directing interactions responsible for the observed self-assembly. The ferrocene fragments of the macrocycle are in an almost perpendicular conformation. Moessbauer spectroscopy indicates the sole presence of low spin iron (II). The temperature dependence of the magnetic susceptibility is corresponding to a quasi-diamagnetic compound.

The complexation of 1 and 2, using the oxidative addition of the S-S bonds to Pt(0), is also described, leading to the square planar Pt(II) complexes [Pt(PPh3)2(S2CH2CH 2CH-kappa2-S,S)(CH2)4C(O) NH(eta5-C5H4)Fe(eta5-C 5H5)] 4 and [Pt(PPh3)2(S 2CH2CH2CH-kappa2-S,S)(CH 2)4C(O)OCH2(eta5-C 5H4)Fe(eta5-C5H5)] 5, respectively. The reduction of the S-S bond in 1 and 2 yields the corresponding dithiols; these can be deprotonated and treated with ClSiMe3 to prepare [(eta5-C5H5)Fe(eta5- C5H4)NHC(O)(CH2)4CH(SSiMe 3)CH2CH2(SSiMe3)] 7 and [(eta5-C5H5)Fe(eta5-C 5H4)CH2OC(O)(CH2) 4CH(SSiMe3)CH2CH2(SSiMe 3)] 9, respectively. The complexes were characterized via NMR and UV-Vis absorption spectroscopy, cyclic voltammetry and single crystal X-ray diffraction for 1 and 4.
