## Abstract 1,4‐Addition of bis(iodozincio)methane to simple α,β‐unsaturated ketones does not proceed well; the reaction is slightly endothermic according to DFT calculations. In the presence of chlorotrimethylsilane, the reaction proceeded efficiently to afford a silyl enol ether of β‐zinciomethyl
