Abstract

The effective synthesis of 1,2-diarylethanones was achieved using palladium(II) acetate [Pd(OAc)2] and silver triflate (AgOTf) as cocatalysts from various oxabenzonorbornadiene derivatives and substituted arylacetylenes via tandem reactions under mild conditions. Exploration of the oxabenzonorbornadiene substrates showed that the 1,2-diarylacetylenes were obtained from adjacent alkoxy substituted oxabenzonorbornadiene derivatives. Preliminary mechanistic studies indicate that the AgOTf served as an indispensable catalyst, and the mechanism of the tandem reaction was proposed.
