The oxidation of a set of sulfur (3a-d, 4a-f, 5a-d, 6a-b) and phosphorus (7, 8, 9, 10a-c, 11, 12) derivatives of ferrocene have been analyzed by cyclic voltammetry and chrono-potentiometry. The results were compared with those of the parent compounds 2a and 2c to determine the effects of the substituent R on sulfur or phosphorus and of the oxidation state of the heteroatom. Ferrocenyl sulfur derivatives (sulfides 3, sulfoxides 4, and sulfones 5) showed a quasi-reversible oxidation at all sweep rates (50 to 300 mV s-1). S(O)-R groups behave as very strong electron-withdrawing substituents, stronger then their C(O)-R analogs. The ferrocenyl phosphine oxidation, generally irreversible, becomes quasi-reversible when the phosphorus atom is already oxidized or coordinated by Lewis acids. CNRS-Gauthier-Villars.

Despite a well-developed and growing body of work in Cu catalysis, the potential of Cu to serve as a photocatalyst remains underexplored. Reported herein is the first example of visible-light-induced Cu-catalyzed decarboxylative C(sp3)?H alkylation of glycine for preparing alpha-alkylated unnatural alpha-amino acids. It merits mentioning that the mild conditions and the good functional-group tolerance allow the modification of peptides using this method. The mechanistic studies revealed that a radical?radical coupling pathway is involved in the reaction.

4-Bromotrifluoromethyl benzene efficiently undergoes oxidative addition to palladium(0) precursors to give phosphine stabilized bromo(4- trifluoromethylphenyl)palladium(II) complexes in high yields. Exchange of the bromo and the phosphine ligands allows further derivatization of these compounds. The solid state structures of two palladium(II) complexes of the type (L-L)Pd(Br)(C6H4CF3), with L-L either performing cis or trans coordination could be elucidated.

Application of 12150-46-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8

The design and synthesis of a new type of topologically chiral [2]catenane is reported. The compounds are formed easily by self-assembly on reaction of the oligomeric digold(I) diacetylide precursor complex [{4-BrC6H4CH(4-C6H4 OCH2CCAu)2}n] with diphosphine ligands. Reactions with the diphosphines PP = bis(diphenylphosphinophoshino)acetylene, trans-l,2-bis(diphenylphosphino)ethylene, bis(diphenylphosphino)ethane, and 1,1?-bis(diphenylphosphino)ferrocene yield simple ring complexes [4-BrC6H4CH(4-C6H4 OCH2CCAu)2(mu-PP)] as the only products, since the spacer groups in the diphosphines are not long enough or are too bulky to allow catenane formation. Reaction with PP = bis(diphenylphosphino)-propane or bis(diphenylphosphino) butane gave [2]catenane complexes [{4-BrC6H4CH(4-C6H4 OCH2CCAu)2-(mu-PP)}2], whose structures are confirmed crystallographically. The macrocyclic ring compounds have Cs symmetry but, as a result of the presence of the unsymmetrical “hinge group” 4-BrC6H4CH, the [2]catenanes have C2 symmetry and so are topologically chiral. In favorable cases, the formation of the [2]catenane can be proved by NMR spectroscopy since catenane formation leads to nonequivalence of most ring atoms. The formation of the [2]catenanes was successfully predicted based on the conformation of the precursor bis(phenol), and it is argued that the methods used should be more generally applicable to the synthesis of functionally substituted supermolecules of interest for application in molecular devices.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8, Computed Properties of C34H28FeP2

Reactions of the platinum complexes cis-[PtCl2(PPh 3)2], [PtCl2(dppf)], or [PtCl 2(dppe)], and the palladium complexes, [PdCl2(PPh 3)2] or [PdCl2(dppe)], with bis(cyanomethyl)sulfone NCCH2SO2CH2CN in methanol with added trimethylamine base gave the new cyano-substituted metallathietane-3,3-dioxide complexes [M{CH(CN)SO2CH(CN)}L 2] (M = Pd, Pt) in good yields and purities. 1H and 31P{1H} NMR spectroscopy indicates that (in the majority of cases) the products are formed as a mixture of cis and trans isomers, with regard to the disposition of the cyano groups across the four-membered ring. An X-ray structure determination on a crystal of [Pd{CH(CN)SO2CH(CN)} (PPh3)2] showed it to be of the cis isomer, the first structurally characterized cis isomer of this type of complex. The four-membered palladacyclic ring is highly planar, in contrast to other metallathietane-3,3- dioxide complexes that have puckered rings. Factors influencing the relative abundances of the two isomers of [Pd{CH(CN)SO2CH(CN)}(PR 3)2] have been investigated by means of NMR spectroscopy and DFT calculations.

Herein we describe the design and preparation of inexpensive, air-stable nickel phosphite-based catalysts for use in the C-N cross-coupling reaction. The combination of nickel tetrakis(triphenyl phosphite) {Ni[P(OPh) 3]4} and 1,1′-bis(diphenylphosphino)ferrocene (dppf), and in particular a newly developed catalyst (dppf)Ni[P(OPh)3] 2, were found to be extremely effective in catalyzing a range of amination reactions of anilines and amines with aryl chlorides. This new catalyst system offers an alternative to the bis(cyclooctadienyl)nickel [Ni(COD)2] and palladium(0) catalysts commonly used for C-N bond formation.
