Abstractmagnified imageN‐Heterocyclic carbene (NHC)‐catalyzed ketone/imine hydrosilylation, silane alcohol condensation and asymmetric ketone hydrosilylation reactions were demonstrated for the first time over solid, main‐chain poly‐NHC particles. The stable and robust poly‐NHC particles were easily recovered, and exhibited good catalytic recyclability. A novel chiral induction protocol with a cheap and easily accessible secondary alcohol as the chiral source was also developed in this catalytic system.

This manuscript describes two catalytic methods for silylether synthesis using Grubbs’ catalyst Cl2(PCy3)2RuCHPh. Silylethers are obtained from the reaction of a variety of silanes with alcohols by dehydrogenative condensation and by the hydrosilylation of carbonyl compounds. Both reactions occur under neat conditions.

Hydrosilylation of terminal alkynes with a variety of silanes catalyzed by Cl2(PCy3)2RuCHPh (1) affords mainly the Z-isomer via trans addition in excellent yields. The presence of a hydroxyl group in close proximity to the triple bond was observed to exert a strong directing effect, resulting in the highly selective formation of the α-isomer.
