Iron-Catalyzed Hydrosilylation of Aldehydes and Ketones under Solvent-Free Conditions
摘要:
Exposure of aldehyde or ketone to 1 mol % BIAN-Fe(C7H8) complex in the presence of diphenyl silane affords the corresponding protected alcohol in excellent yields, under mild reaction conditions. Aldehydes and ketones are reduced cleanly in the presence of a broad range of functional groups under solvent-free conditions.

Keep it simple: A variety of ketones and two aldehydes underwent efficienthydrosilylation under mild conditions in the presence of the title complex (see scheme; R,R′=H, alkyl, aryl). In some cases, a catalyst loading of just 0.01–0.03 mol % was sufficient. This catalyst may provide a simple, cost‐effective, and environmentally benign alternative to currently employed methods for the hydrosilylation

An isolable 14-electron ironbis(supersilyl) complex, Fe[Si(SiMe3)3]2(THF)2, was successfully synthesized from the reaction of FeBr2 with K[Si(SiMe3)3] and its structure was unambiguously determined by single-crystal X-ray diffraction analysis. The complex is coordinatively unsaturated and exhibits high catalytic activity toward the hydrosilylation of carbonyl compounds and the reductive silylation

related pincer systems. The analysis of the reaction mechanism allows for the synthesis and characterization of a nickel alkoxide derivative by insertion of the carbonyl moiety into the Ni−H bond. Combined experimental and theoretical analysis (DFT) support a reaction mechanism that involves the initial formation of an alkoxide complex followed by reaction with the silane to release the corresponding

were optimized with different silanes and efficient dehydrogenative coupling was achieved by using triethoxysilane and diphenylsilane. Various alcohols and phenols and a limited number of carboxylic acids were converted into the corresponding silyl ethers and silyl esters. A range of functional groups such as chloro, nitro, methoxy, carbonyl and carbon–carbonmultiplebonds are tolerated in the reaction

efficient and regioselective hydrosilylation of epoxides co-catalyzed by a pentacarboxycyclopentadienyl (PCCP) diamide nickel complex and Lewis acid is reported. This method allows for the reductive opening of terminal, monosubstituted epoxides to form unbranched, primaryalcohols. A range of substrates including both terminal and nonterminal epoxides are shown to work, and a mechanistic rationale
