2,4,6-Tris[bis(trimethylsilyl)methyl]phenyllithium (TbLi) gave a novel 1,3-silicon rearrangement product above −30 °C, while the treatment of TbLi with some electrophiles also afforded 1,3-silicon rearrangement products even at −78 °C probably via single electron transfer mechanism.
2,4,6-Tris [双(三(三甲基硅烷基)甲基]苯基锂(TbLi)在-30°C以上产生了一种新型的1,3-硅重排产物,同时用一些亲电试剂处理TbLi也提供了1,3-硅重排甚至可以在-78°C的温度下通过单电子转移机理生成产物。
