The catalyst, [Rh(Ph2PCH2CH2PPh2)]+ engages in a consecutive catalytic sequence where allylic alcohols, β-keto alcohols and α,β-unsaturated aldehydes in the presence of dihydrosilanes are first converted to the corresponding monohydrosilyl ethers, which are then cyclized.

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.

(Chemical Equation Presented) Worth their weight in gold: Au/CeO 2 nanoparticles are a highly active catalyst for the hydrosilylation of a large variety of unsaturated compounds with high chemo- and regioselectivity. To understand the nature of the catalytic active sites, AuI and AuIII phosphine-free stable organogold complexes and their supported counterparts were prepared and their relative activity towards hydrosilylation was elucidated.
Asymmetric catalysis. Production of chiral diols by enantioselective catalytic intramolecular hydrosilation of olefins

Rhodium(I) chiral diphosphine complexes efficiently and rapidly catalyze the intramolecular hydrosilation of silyl ethers derived from allylic alcohols. The efficiency and rates of intramolecular hydrosilations were determined for a variety of silyl and olefin substituents. The catalysts were found to tolerate a wide variety of silyl substituents, although terminal alkyl olefin substituents were found to retard catalysis. Terminal aryl olefin substituents were found to be hydrosilated efficiently and at reasonable rates. One of the chiral catalysts is highly enantioselective for terminal aryl olefin substituents. Almost quantitative ee's are obtained. Moreover, the ee's are only slightly sensitive to aryl and olefin substituents, suggesting that this enantioselective catalysis can provide a wide range of chiral species. Oxidative cleavage of the hydrosilation products gives chiral diols.
