The Suzuki-Miyaura reaction of the bis(triflate) of 3,4-dihydroxybenzophenone with two equivalents of boronic acids gave 3,4-diarylbenzophenones. The reaction with one equivalent of arylboronic acids resulted in site-selective attack onto carbon atom C-4. 3,4-Diarylbenzophenones containing two different aryl groups were prepared by sequential addition of two different boronic acids.
