bond migration during photooxidation of a sulfide is reported. Evidence is presented which demonstrates that the double bond migration is not a result of a prior acid-catalyzed rearrangement of an unrearranged sulfone precursor. This unusual observation is used to argue that the sulfone is formed via rearrangement of a hydroperoxy sulfonium ylide intermediate.
报道了在硫化物的光氧化过程中伴随双键迁移形成砜的第一个例子。提出的证据表明双键迁移不是未重排的砜前体在先的酸催化重排的结果。这种不寻常的观察结果被认为是通过氢过氧sulf内酯中间体的重排形成了砜。
