Abstract: The palladium(0)-catalyzed Suzuki cross-coupling reaction of the bis(triflates) of 2,4′-dihydroxybenzophenones afforded 2,4′-diarylbenzophenones. The Suzuki-Miyaura reaction of the bis(triflate) of 3,4-dihydroxybenzophenone with two equivalents of boronic acids gave 3,4-diarylbenzophenones. The Sonogashira cross-coupling reactions of the same substrate display remarkable compatibility with Suzuki reactions.The palladium(0)-catalyzed Suzuki cross-coupling reaction of the bis(triflates) of methyl 2,5-dihydroxybenzoate and methyl 2,4-dihydroxybenzoate afforded p-terphenyls and m-terphenyls respectively.
