description The invention relates to novel boronizing agent dimethylamino boronic acid pinacol ester PinB(DMA) the structure of which is in the specification. The specific synthesis steps are as follows: reacting raw material B(NME2)3 with pinacol for 2-5 hours under the solvent-free condition at the temperature of 50-70 DEG C; and distilling under the vacuum condition of minus 0.1 Mpa, and collecting fraction of 45-50 DEG C, namely the fraction is the product. The PinB(DMA) provided by the invention has the characteristics that water sensitivity is low, structure is stable, ultralow temperature reaction can be avoided when the PinB(DMA) participates in boronization reaction, and the like; and the market value of the PinB(DMA) is important. Compared with the similar processes, the synthesis process of the boronizing agent in the invention has the obvious characteristics of simple reaction steps, mild process condition, no solvent reaction, good process stability and simple post-treatment; and the boronizing agent prepare
