Stepwise carbon dioxide hydrosilylation catalyzed by bimetallic complexes [CpM(CO)2(μ-CO)···Pd(ButPCP)]

The interaction of bimetallic (ButPCP)Pd···(OC)M(CO)2 Cp (M = Mo, W) complexes with PhSiH3 leads to an efficient heterolytic splitting of Si–H bond that is a primary step in catalytic hydrosilylation of CO2. The reaction can be stopped at the formate level in the presence of the above complexes while proceeds further when catalyzed by (ButPCP)PdH.
