Transition metal-catalyzed dehydrogenative silylation of ketones with amine and halide as cocatalysts

It was found that dehydrogenative silylation of ketones with hydrosilanes proceeds in the presence of a transition metal catalyst such as palladium on carbon or iridium carbonyl, with amine and halide as cocatalysts, to give the corresponding silyl enol ethers in good yields. The present reaction is...

Description
Summary:It was found that dehydrogenative silylation of ketones with hydrosilanes proceeds in the presence of a transition metal catalyst such as palladium on carbon or iridium carbonyl, with amine and halide as cocatalysts, to give the corresponding silyl enol ethers in good yields. The present reaction is applicable for a variety of ketones and hydrosilanes with complete regioselectivity. Dehydrogenative silylation of ketones with hydrosilanes proceeds in the presence of a transition metal catalyst with amine and halide as co-catalysts to give the silyl enol ethers in good yields.
