An efficient copper-catalyzedcarbenoidinsertion reaction of α-diazo carbonyl compounds into Si–H and S–H bonds was developed. A wide range of α-silylesters and α-thioesters was obtained in high yields (up to 98%) from α-diazoesters using 5 mol% of a simple copper(I) salt as catalyst. Using 0.05 mol% of the same catalyst, α-diazoketones led to α-silylketones in low to good yields (up to 70%).

A new route fromα-bromoketones to α-trailkylsilylketones has been developed which demonstrates the viability of halogen-metal exchange vis-a-vis nucleophilic attack at silicon, even with the unhindered trimethylsilyl group.
