Pinacol vinylboronate Use and Manufacturing

Methods of Manufacturing

Under a nitrogen atmosphere, 193 g of pinacol and 14 g of 2, 6-di-t-butyl-4-methylphenol were charged in a 1 L reaction flask, To 85-90 ° C, until the pinacol is completely melted, the slow trickle-down of the intermediate reaction, attention to control the dropping rate, then atmospheric steamDistillation device, the reaction of diisopropylamine separation, after the end of the reaction temperature to obtain colorless transparent liquid vinyl boronic acid which252 g of the alcohol ester, and GC: 99.1percent (excluding the polymerization inhibitor).
