Synthesis of divalent ytterbium terphenylamide and catalytic application for regioselective hydrosilylation of alkenes

Author affiliations

Abstract

The dimeric heteroleptic ytterbium amido complex [(2,6-(3,5-Me2C6H3)2C6H3NH)Yb(N(SiMe3)2)]2 (1) has been prepared and characterized. This divalent terphenylamido complex enabled highly regioselective hydrosilylation of various terminal alkenes with very low catalyst loadings. The reaction of 1 with phenylsilane at high temperature led to the dehydrogenative coupling of silane with a terphenylamide ligand and redistributions of amide ligands via a hypervalent silane intermediate, which has been spectroscopically characterized.
