Hydrosilylation of Ketone and Imine over Poly-N-Heterocyclic Carbene Particles

N-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.
