The development of a palladium-catalyzed sp3–sp2 Suzuki–Miyaura cross-coupling of B-alkyl-N-methyliminodiacetyl (B-alkyl MIDA) boronates and (hetero)aryl bromides is reported. This transformation is tolerant of a variety of functional groups (F, NO2, CN, Cl, COCH3, and CHO). B-Alkyl MIDA boronates allow an efficientcross-coupling reaction directed toward the synthesis of unsymmetrical methylene diaryls
