Abstract

Abstract The scope of the B (C 6 F 5) 3-catalyzed hydrosilylation of (X) Ph–CH= O and (X) Ph–C (R)= O was expanded to include a large set of substitutents (X= H, p-Me, o-Me, pF, oF, p-Cl, p-Br, p-NO 2, m-NO 2, p-Et; R= Me or CF 3). Reactions proceed at room temperature with high chemoselectivity in a host of solvents (toluene, benzene, CCl 4, 1, 2- dichloroethane, and methylcyclohexane), or under solventless conditions, with ...
