2-boronic acid pinacol ester-9, 9 '-spirobis (xanthene) and synthesis method thereof

The invention discloses 2-boronic acid pinacol ester-9, 9 '-spirobis (xanthene) and a synthesis method thereof, and belongs to the field of organic chemical synthesis. The structural formula of the 2-bromo-9, 9 '-spirobis (xanthene) is as follows: # imgabs0, and the 2-bromo-9, 9'-spirobis (xanthene) is synthesized by the following method: reacting 2-bromoxanthone serving as an initial raw material with phenol to synthesize 2-bromo-9, 9 '-spirobis (xanthene), and then carrying out Suzuki-Miyaura reaction to synthesize the 2-bromo-9, 9'-spirobis (xanthene). The synthesis method disclosed by the invention is simple to operate and low in production cost, the product content is greater than 99.9%, the industrial production and application requirements can be met, the synthesis method is suitable for industrial production, and the application of the spiro compound as an intermediate in the design and synthesis of an organic photoelectric functional material is expanded. 本发明公开了一种2-硼酸频哪醇酯-9,9'-螺二(氧杂蒽)及其合成方法，属有机化学合成领域
