synthesis of boronic acids has greatly facilitated the two-step, one-potborylation/Suzukicross-couplingreaction between aryl and heteroaryl halides. With use of Buchwald’s second-generation XPhos preformed catalyst, high yields of cross-coupled products were obtained for most substrates. The method also allows an efficient two-step, one-pot synthesis, providing access to three distinct cross-coupled
