Abstract

The bis-N-heterocyclic carbene (NHC) stabilized stannyliumylidene, [^MesTerSn(IMe₄)₂][BArF], (^MesTer = 2,6-Mes₂C₆H₃, Mes = 2,4,6-Me₃-C₆H₂, IMe₄ = 1,3,4,5-tetramethylimidazol-2-ylidene, BArF = (3,5-(CF₃)₂-C₆H₅)₄B), was isolated in the reaction of (^MesTer)SnCl with two equivalents of IMe₄, followed by one equivalent of NaBArF. This stannyliumylidene acts as a precatalyst for the homogeneous hydrosilylation of CO₂. Experimental mechanistic studies and quantum chemical calculations have been conducted to elucidate the catalytically active species and the mechanism of the catalytic reaction, revealing the stannyliumylidene [^MesTerSn(CO₂IMe₄)₂][BArF], which is formed in the presence of CO₂ as the catalytically active species.

期刊介绍： Chemical Science is a journal that encompasses various disciplines within the chemical sciences. Its scope includes publishing ground-breaking research with significant implications for its respective field, as well as appealing to a wider audience in related areas. To be considered for publication, articles must showcase innovative and original advances in their field of study and be presented in a manner that is understandable to scientists from diverse backgrounds. However, the journal generally does not publish highly specialized research.
