| Research Abstract |
Preparation of a metal carbenoid by the reaction of carbon dioxide with disilane in the presence of transition metal catalyst has been investigated. We first investigated the cleavage of the silicon–silicon bond of disilane by transition metal catalysts. After extensive screening of metal catalysts, we found that Pd, Pt, and Cu catalysts were suitable for the silicon–silicon bond cleavage. For the reaction with carbon dioxide, further investigation of catalyst system using several ligands demonstrated that NHC-complex showed high reactivity toward the metal carbenoid formation. Indeed, the reaction of the carbenoid with styrene afforded the product that included carbon dioxide as a C1 unit.
