Title full: Synthesis and characterization of 1,1?-bis[(N-methyl-N-phenyl)aminomethyl(ethyl)]ferrocenes. Crystal structures of [Fe{(eta5-C5H4)-C(C6H 5){double bond, long}N-CH2C6H4CH3-4} 2] and 2[Fe{(eta5-C5H4)-CH2N (CH3)-C6H4OCH3-4}2] ¡¤ 1/4H2O. Direct or catalytic condensation of diacylferrocenes (acyl = formyl, acetyl, and benzoyl) and anilines or benzylamines with titanium tetrachloride as a catalyst resulted in the corresponding diimines 1-3, respectively. Reduction of these imines with sodium borohydride or lithium aluminum hydride/aluminum chloride in THF yielded 1,1?-bis[(N-phenyl)aminomethyl(ethyl)]ferrocenes (4, 5) and 1,1?-bis[(N-benzyl)aminobenzyl]ferrocenes (6), respectively. Reductive methylation of 4-6 with aqueous formaldehyde, cyanoborohydride and acetic acid only afforded 1,1?-bis[(N-methyl-N-phenyl)aminomethyl(ethyl)]ferrocenes (7, 8). 1,1?-Bis[{(N-methyl-N-benzyl)amino}benzyl]ferrocenes (9) were not obtained, probably due to their debenzylation under the acidic conditions. The molecular structures of 3g and 7a were determined by single crystal X-ray analysis.

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.

ChenPhos: Highly modular P-stereogenic C1-symmetric diphosphine ligands for the efficient asymmetric hydrogenation of alpha-substituted cinnamic acids

These cats are purrfectionists: The ChenPhos ligands (see structure) showed dramatically higher catalytic activity in the title reaction than their C 2-symmetric predecessor with two dimethylaminoethyl-substituted ferrocenyl(phenyl)phosphanyl groups. The ready accessibility, extreme air stability, and high enantioselectivity, activity, and productivity of these ligands make them very promising for a wide range of practical applications.

The coupling of the ferrocenyl and the thiophene moieties has been realized using the Negishi C,C cross-coupling reaction protocol. Compounds 3a and 4c were structurally characterized by single-crystal X-ray diffraction studies. In electrochemical measurements the ferrocenyl redox potential depends on the particular substitution at the ferrocenyl and the thiophene unit. Moreover, UV/Vis/NIR studies showed ligand-to-metal charge transfer (LMCT) interactions, which occur after oxidation and are shifted bathochromically as the donor-acceptor energy gap decreases. Using different substituents, possessing electron-withdrawing or donating capabilities, allows adjusting the energy difference between the ferrocenium-acceptor unit and the donating thiophene system.

Dye regeneration kinetics in dye-sensitized solar cells

The ideal driving force for dye regeneration is an important parameter for the design of efficient dye-sensitized solar cells. Here, nanosecond laser transient absorption spectroscopy was used to measure the rates of regeneration of six organic carbazole-based dyes by nine ferrocene derivatives whose redox potentials vary by 0.85 V, resulting in 54 different driving-force conditions. It was found that the reaction follows the behavior expected for the Marcus normal region for driving forces below 29 kJ mol-1 (delta = 0.30 V). Driving forces of 29-101 kJ mol-1 (delta = 0.30-1.05 V) resulted in similar reaction rates, indicating that dye regeneration is diffusion controlled. Quantitative dye regeneration (theoretical regeneration yield 99.9%) can be achieved with a driving force of 20-25 kJ mol-1 (delta ? 0.20-0.25 V).

Ferrocenyl aryl ethers can be synthesized in good yields by Cu(I)/phosphine-catalyzed coupling reactions from iodoferrocene or 1,1?-dibromoferrocene and various phenols in toluene, using Cs2CO3 or K3PO4 as a base. For the first time a solid-state structure of a ferrocenyl-1,1?-diaryl ether [1,1?-di(4-tert-butylphenoxy)ferrocene] has been determined from single-crystal X-ray data.

Electron transfer in mixed-valence polyferrocenium cations: Preparation, electrochemistry, and 57Fe Moessbauer characteristics

Convenient new methods are developed for the preparation of 1?,1??-disubstituted triferrocenes and tetraferrocenes that can be oxidized with iodine to a new series of mixed-valence compounds. The X-ray structures of 1?,1??-diethyltriferrocene, 1?,1??-dimethoxymethyltriferrocene, and 1?,1??-dimethoxymethyltetraferrocene have been determined at 298 K. The rates of intramolecular electron transfer in these mixed-valence cations were estimated by variable-temperature 57Fe Moessbauer experiments. The features in all 80 and 300 K spectra include two doublets, one with a quadrupole splitting (DeltaEQ) of ?2 mm s-1 (Fe(II) site) and the other with DeltaEQ = ?0.3 mm s-1 (Fe(III) site). This pattern of two doublets is expected for a mixed-valence biferrocenium cation that is valence-trapped on the time scale of the Moessbauer technique (electron-transfer rate Recommanded Product: 1,1′-Dibromoferrocene, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 1293-65-8
