Cyclopentadienyl N-heterocyclic carbene–nickel complexes as efficient pre-catalysts for the hydrosilylation of imines†
Abstract
The in situ generated nickel hydride complex, [Ni(Mes2NHC)HCp], and its cationic analogue, [Ni(Mes2NHC)(NCMe)Cp](PF6), are efficient and chemoselective pre-catalysts for the hydrosilylation of both aldimines and ketimines under mild conditions.
