Cobalt(II) complexes capable of catalyzing alkene hydrosilylation in the absence of external activators are rarely known, and their activation mode has remained poorly understood. We present here that cobalt(II) amide complexes, [Co(N(SiMe3)2)2] and its NHC adducts [(NHC)Co(N(SiMe3)2)2] (NHC = N-heterocyclic carbene), are effective catalysts for the hydrosilylation of alkenes with tertiary silanes. Mechanistic studies revealed that cobalt(II) amides can react with hydrosilane to form cobalt(I) species, silylamide, and hydrogen, which serves as the entry to the genuine catalytically active species, presumably cobalt(I) species, for the cobalt-catalyzed hydrosilylation reaction.

Abstract Rh(PPh3)3Cl-polyethyleneglycol (PEG) functionalized ionic liquids with various anions were used as a catalytic system for the hydrosilylation reaction of alkenes. The influence of the anion of the ionic liquid has been investigated. It was found that the anion has an impact on the catalytic activity and selectivity. [PEG400DIL][PF6]-[Rh(PPh3)3Cl] shows an improved catalytic performance towards the hydrosilylation reaction of alkenes. The scope of alkenes and recycling of the catalytic system have been investigated.
