Abstract

An original bis(iminophosphorane)phosphine NPN ligand was synthesised and coordinated to CoII. Both the ligand and the complex were characterised by multinuclear NMR spectroscopy and X-ray crystallography. The CoII complex (1.5 mol%) in the presence of NaOMe (3 mol%) catalyses the hydrosilylation of olefins within a few hours at 60 °C. Both 1-alkenes and less reactive internal ones built upon a norbornene skeleton were efficiently transformed.
