Abstract

1-Alkynyldiphenylstibines react with acyl chlorides in dichloroethane in the presence of a palladium (0) or (II) catalyst to afford alkynyl ketones by cross-coupling reaction in good to moderate yields. These reactions are highly substituent-selective in that only the alkynyl group could be transferred from the antimony compounds, even in the presence of a large excess of acyl chlorides.
