Stable bis(silyl)nickel complexes with o-carboranyl unit: a facile double silylation of alkynes and alkenes

Abstract

The reaction of o-bis(dimethylsilyl)carborane with Ni(PEt₃)₄ in pentane affords the reactive intermediate,[o-(SiMe₂)₂C₂B₁₀H₁₀]Ni(PEt₃)₂ 2; the facile double silylation of alkynes catalyzed by 2 is reported.
