Abstract

Amine carboxyborane enabled efficient halogen atom transfer (XAT) with 1°, 2°, and 3° alkyl bromides, resulting in Giese addition products with various electron-deficient double bonds. Moreover, direct addition of several boryl radicals was also possible using several ligated carboxyboranes.

烷基溴与胺羧基硼烷的合成反应
胺羧基硼烷使10、20和30烷基溴之间的卤素原子转移(XAT)有效,从而产生具有各种缺电子双键的吉斯加成产物。此外,用几个连接的羧基硼烷也可以直接加成几个硼基自由基。
