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.

Rhodium(I) chiral diphosphine complexes efficiently and rapidly catalyze the intramolecular hydrosilation of silylethers derived fromallylicalcohols. The efficiency and rates of intramolecular hydrosilations were determined for a variety of silyl and olefin substituents. The catalysts were found to tolerate a widevariety of silyl substituents, although terminal alkyl olefin substituents were found to

The catalyst, [Rh(Ph(2)PCH(2)CH(2)PPh(2))](+) engages in consecutive catalytic sequence where allylic alcohols, beta-keto alcohols and alpha,beta-unsaturated aldehydes in the presence of dihydrosilanes are first converted to the corresponding monohydrosilyl ethers, which are then cyclized.
