The generation of tertiary, secondary, and primary alkyl radicals has been achieved by the direct visible-light excita-tion of a boracene-based alkylborate. This system is based on the photophysical properties of the organoboron mole-cule. The protocol is applicable to decyanoalkylation, Giese addition, and nickel-catalyzed carbon-carbon bond for-mations such as alkyl-aryl cross-coupling or vicinal
叔、仲和伯烷基自由基的产生是通过硼苯基烷基硼酸酯的直接可见光激发来实现的。该系统基于有机硼分子的光物理特性。该协议适用于脱氰烷基化、Giese 加成和镍催化的碳-碳键形成,例如烯烃的烷基-芳基交叉偶联或邻位烷基芳基化,从而能够将各种 C(sp3) 片段引入到有机分子。
