B-Alkyl Suzuki–Miyaura cross-coupling of tri- n-alkylboranes with arylbromides bearing acidic functions under mild non-aqueous conditions

Abstract

An efficient and chemoselective Pd-catalyzed B-alkyl Suzuki–Miyaura cross-coupling of tri- n-alkylboranes with arylbromides possessing acidic functions is described. This protocol features the relatively weak base Cs 2CO 3 and mild non-aqueous conditions. Aldehydes, ketones, nitriles, and chloro substitution are all tolerated.
