Electrooxidation of α-phenyl substituted β-hydroxy sulfides in dichloromethane in the presence of chloride ions as the electrolyte results in a novel pinacol-type rearrangement to give 2-phenyl substituted ketones like 2-phenylcycloalkanone as the ring expansion product. The rearrangement is induced by an electrogenerated chloronium ion, which effects, instead of common C-C scission, a selective C-S
在存在
氯离子作为电解质的情况下,
二氯甲烷中的α-苯基取代的β-羟基
硫化物在
二氯甲烷中的电氧化会产生新颖的
频哪醇型重排,从而产生2-苯基取代的酮,如2-苯基环烷酮作为扩环产物。重排是由电生成的
氯鎓离子引起的,它代替普通的CC分裂,而是选择性地CS裂解β-羟基
硫化物,而不是普通的CC分裂。
