Doubly radical: A novel entry to α,n-didehydrotoluene (DHT) diradicals is disclosed and proceeds through the photochemical activation of (chlorobenzyl)trimethylsilanes with chloride loss and elimination of the SiMe(3) (+) group. The products formed in solution are indicative of the intermediacy of the three isomers of the α,n-DHT.
本文揭示了一种新型的α,n-去氢甲苯(DHT)双自由基的生成途径,该途径通过氯代苄基三甲基硅烷的光化学活化进行,同时伴随着氯原子的缺失和 SiMe(3)(+)基团的消除。在溶液中形成的产物表明了α,n-DHT 的三种异构体的中间体的存在。
