The use of bis-boronic acid for the direct synthesis of boronic acids has greatly facilitated a two-step, one-pot borylation/Suzuki cross-coupling reaction 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.
