Abstract
Alkynylsilanes and allyltrimethylsilane undergo smooth coupling with acid chlorides in the presence of 5 mol% of indium tribromide under mild conditions to afford the corresponding α,β-acetylenic ketones and β,γ-unsaturated ketones in excellent yields in a short reaction time with high selectivity.
Key words
indium reagents - acid chlorides - α,β- and β,γ-unsaturated ketones
