Base free transformation of PhSSPh to sulfides, PhSR (R= alkyl, benzyl, allyl, acyl) and N-acetyl-L-cystine to mercapturic acids [AcNHCH(COOH)CH2SR, R= alkyl, benzyl, allyl, acyl] have been achieved using Zn/cat. CoCl2/organic halide in MeCN at room temperature.
PhSSPh的无碱转化为硫化物,PhSR(R =烷基,苄基,烯丙基,酰基)和N-乙酰基-L-胱氨酸转化为巯基酸[AcNHCH(COOH)CH 2 SR,R =烷基,苄基,烯丙基,酰基]使用锌/催化剂已经实现。室温下在MeCN中的CoCl 2 /有机卤化物。
