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.
