A highly efficient water-accelerated palladium-catalyzed reaction of gem-dibromoolefins with a boronicacid via a tandem Suzuki−Miyaura coupling and direct arylation is reported. A wide range of aryl, alkenyl, and alkyl boronicacids, as well as a variety of substitution patterns on the phenyl ring, are tolerated. Additionally, mechanistic studies were conducted to ascertain the order of the couplings
