A Homobimetallic Frustrated Lewis Pair Cobalt Catalyst for the Methanolysis of Hydrosilanes.

ABSTRACT: The bimetallic Co(I)/Co(-I) complex [Co(CO)₂(κ³-P,N,P-PN^HP)][Co(CO)₄] (1) has shown excellent activities in the methanolysis of hydrosilanes, surpassing the related bimetallic Co(I)/Co(-I) complex [Co(CO)(PMe₂Ph)(κ³-P,N,P-PN^HP)][Co(CO)₄] (2), the Co(II) complex [Co(Cl)₂(κ³-P,N,P-PN^HP)] (3), and the Co(I) complex [Co(CO)₂(κ³-P,N,P-PN^HP)]Cl (4). A comprehensive DFT study of the plausible reaction mechanisms indicates that the enhanced activity of 1 can be attributed to the presence of the [Co(CO)₄]^- anion, which enables a frustrated Lewis pair (FLP) mechanism that provides a low energy pathway for the heterolytic split
