Abstract : For the first time, insertion of an unactivated alkene into the metal-silicon bond of a catalytically active transition metal complex has been demonstrated. In addition, formation of CH4, not SiMe4, when (CO)4Co-Me is reacted with Me3SiH, is clearly inconsistent with the traditional Chalk-Harrod mechanism for transition metal catalyzed hydrosilation of olefins. Both reactions are key steps in a new mechanism for hydrosilation. Keywords: Photocatalysis, Hydrosilation, Olefin insertion, Catalysis.
