Abstract

The coupling reaction of pinacolborane with aryl halides or triflates in the presence of a catalytic amount of PdCl2(dppf) together with Et3N provided arylboronates in high yields. The use of a tertiary amine as base was crucial for the selective formation of the boron-carbon bond. The reaction tolerates a variety of functional groups such as carbonyl, cyano, and nitro groups.
