The asymmetric hydrogenation of silylimines was first developed by using a palladium complex of a P-stereogenic diphosphine ligand as the catalyst, affording the valuable chiral α-aminosilanes with quantitative conversions and excellent enantioselectiviti

An efficient synthesis of functionalized tertiary α-silyl alcohols by an enantio- and diastereoselective copper-catalyzed three-component coupling of 1,3-dienes, bis(pinacolato)diboron, and acylsilanes is reported. The reaction proceeds well with different 1,3-dienes and a broad range of aryl- as well as alkenyl- but also alkyl-substituted acylsilanes. The target compounds are formed with high regio-, diastereo-, and enantioselectivity (up to 99 % ee and d.r. >20:1) and are highly versatile synthetic building blocks.

Acylsilanes were obtained efficiently from dedithioacetalization of 2-silylated 1,3-dithianes using 30% hydrogen peroxide catalyzed by iron(III) acetylacetonate-sodium iodide. The use of niobium(V) chloride as a catalyst instead of iron(III) acetylacetonate was also effective, except in synthesizing some acyltrimethylsilanes.
