investigate the effects of various carboxylate bases and their corresponding counterions on reactivity. Our results highlight potassium pivalate as producing exceptional rate acceleration. To the best of our knowledge this base has not previously been reported for use in Miyaura borylations. Diethanolamine transesterification is also reported as a facile and robust boronate isolation protocol. Successful
