摘要

本文建立了一种硼酯直接氧化羰基的方法。在可见光和O2气氛的照射下，可以得到中高收率的酮类和醛类化合物。采用四丁基三溴化铵(TBATB)作为催化剂，避免了金属基(光)催化剂的使用。α-硼烷基自由基被认为是该氧化过程的关键中间体。

Photoinduced oxidation of benzylic boronic esters to ketones/aldehydes via α-borylalkyl radicals†

A method for direct oxidation of boronic esters to the carbonyl groups has been established herein. Under the irradiation of visible light and O₂ atmosphere, ketones and aldehydes can be obtained in moderate to excellent yields. Using tetrabutylammonium tribromide (TBATB) as the catalyst, this procedure avoids using of metal-based (photo)catalysts. α-Borylalkyl radicals have been proposed as the key intermediates of this oxidation process.
