The insertion of a nonactivated alkene into the MSi bond of a catalytically active transition‐metal complex has been demonstrated for the first time. Furthermore, the formation of CH 4 instead of SiMe 4 in the reaction of [(CO) 4 CoMe] with Me 3 SiH is clearly inconsistent with the traditional Chalk–Harrod mechanism for the transition‐metal‐catalyzed hydrosilation of olefins. Both reactions are key steps in a new proposal for the mechanism of this reaction.
