We have established a facile and efficient protocol for the generation of germyl radicals by employing photo‐excited electron transfer (ET) in an electron donor‐acceptor (EDA) complex to drive hydrogen‐atom transfer (HAT) from germyl hydride (R3GeH). Using a catalytic amount of EDA complex of commercially available thiol and benzophenone derivatives, the ET‐HAT cycle smoothly proceeds simply upon blue‐light irradiation without any transition metal or photocatalyst. This protocol also affords silyl radical from silyl hydride.

通过 EDA 催化的 ET-HAT 过程产生可见光驱动的甲自由基

我们建立了一种简便有效的方案，通过在电子供体-受体（EDA）复合物中采用光激发电子转移（ET）来驱动甲硅烷基氢化物（R3GeH）的氢原子转移（HAT），从而产生甲芽自由基。使用催化量的市售硫醇和二苯甲酮衍生物的 EDA 络合物，ET-HAT 循环只需蓝光照射即可顺利进行，无需任何过渡金属或光催化剂。该方案还从甲硅烷基氢化物提供甲硅烷基。
