Synthesis

151293-63-9
75927-49-0
Under nitrogen protection, 193 g of pinacol and 14 g of 2,6-di-tert-butyl-4-methylphenol were added to a 1 L reaction flask and heated to 85-90 °C until the pinacol was completely melted. The intermediate reactants were added slowly dropwise, taking care to control the rate of dropwise acceleration. Subsequently, diisopropylamine was isolated by distillation using an atmospheric pressure steam distillation apparatus. Upon completion of the reaction, a colorless and transparent vinylboronic acid pinacol ester liquid product containing 225 g of the target product was obtained, which was analyzed by gas chromatography (GC) with a purity of 99.1% (excluding polymerization inhibitors).
