The addition of carbon dioxide to (tBuPNP)CoH[tBuPNP = 2,6 - bis(di-tert-butylphosphinomethyl)pyridine] resulted in rapid insertion into the Co-H bond to form the corresponding K1- formate complex, which has been structurally characterized. Treatment of (tBuPNP)CoH with PhSiH3 resulted in oxidative addition to form trans-(tBuPNP)CoH2(SiH2Ph), which undergoes rapid exchange with excess free silane. With 0.5 mol % (tBuPNP)CoH, the catalytic hydrosilylation of CO2 with PhSiH3 to a mixture of oligomers containing silyl formate, bis(silyl)acetyl, and silyl ether subunits has been observed.
