Synthesis of 2′,4-diarylbenzophenones through site-selective suzuki-miyaura reactions of bis(triflates) of 2′,4-dihydroxybenzophenones

摘要

Palladium(0)-catalyzed Suzuki cross-coupling reactions of the bis(triflates) of 2′,4-dihydroxybenzophenones afforded 2′,4-diarylbenzophenones. The reactions proceeded with very good site selectivity in favour of the 4-position.
