Abstract

The palladium (0)-catalyzed Suzuki cross-coupling reaction of the bis (triflates) of methyl 2, 5- dihydroxybenzoate and methyl 2, 4-dihydroxybenzoate afforded para-and meta-terphenyls, respectively. The reactions proceeded with very good site selectivity in favor of the sterically less hindered carbon atom.
