A study on catalytic activity of Co and Fe complexes for N2 silylation is presented. It was found that silylene Fe(I) chloride is the most active catalyst among 8 complexes for N2 silylation and 402 equiv. of N(SiMe3)3 were obtained per Fe atom.
Three silyl [PNSiNP] pincer cobalt(III) hydrides, CoIII(H)(Cl)(PMe3)(R′Si(NCH2PR2)2C6H4) (R′ = Me and R = Ph (1); R′ = Ph and R = Ph (2) and R′ = Me and R = iPr (3)), were synthesized. Complexes 2 and 3 are new and have been characterized.
This review summarizes the developments of X-type silyl ligands for transition-metal catalysis, elucidating the unique features of σ-donating ability and trans-influence of silyl–metal catalysts.
In this article, the catalytic performance of acylenolato cobalt(III) hydrides [CoIII(O∩CO)(PMe3)3H] (O∩CO = acylenolato ligand) 1–3 for alkene hydrosilylation was studied.
A common intermediate was computationally identified from the reaction of [RhCl(COD)]2 and the silylphosphine [PhP(o-C6H4CH2SiHiPr2)2], L1, rendering either a Rh monomer (Rh-1) or its corresponding isomerized dimer (Rh-3) with an n-propyl on Si.
