afforded in moderate to good yield accompanied by formation of 9,9′-bis(arylmercapto)fluorene. The major reaction pathway is considered to be a disulfur ylide formation followed by two times of successive Stevens rearrangement or by concerted electron redistribution via [2,3]sigmatropic rearrangement.
用二对甲苯基或二对茴香基二硫化物辐照(> 340 nm)重氮芴的苯溶液后,以中等至良好的收率提供相应的9,9'-双(芳基巯基)联芴基,伴随形成9,9'-双(芳基巯基)芴。主要的反应途径被认为是二硫化氢的形成,随后是两次连续的史蒂文斯重排或通过[2,3]σ向重排的协同电子再分布。
