Abstract
AbstractThe terphenyl amido stannylene‐NHC adducts, HMDS(MesTer)Sn(NHC), (MesTer = 2,6‐Mes2C6H3, Mes = 2,4,6‐Me3‐C6H2, HMDS = N(SiMe3)2, NHC = IMe4, IEt, IMe4 = 1,3,4,5‐tetramethylimidazol‐2‐ylidene, Iet = 1,3‐diethyl‐4,5‐dimethylimidazol‐2‐ylidene), were reacted with benzaldehyde resulting in the formation of HMDS(MesTer)Sn(OCH(Ph)NHC). In the presence of acetophenone, deprotonation occurs to afford the tin enolate (MesTer)Sn(NHC)(OPhC=CH2), via the release of hexamethyldisilamine. This stannylene‐NHC adduct is a catalyst for the homogeneous hydrosilylation of aldehydes and ketones under ambient conditions.
