Unsymmetrical thiocarbonyl disulfides (3) have been easily synthesized in good yields by the reaction of piperidinium dithiocarboxylates with sulfenyl chlorides. In the reaction of these disulfides with nucleophiles (amine and metal alkoxide), both thiocarbonyl carbon and sulfenyl sulfur atom seem to be attacked by nucleophiles. By desulfurization with triphenylphosphine thiocarbonyl disulfides converted
不对称硫代羰基二硫化物 (3) 可以通过哌啶鎓二硫代羧酸盐与亚磺酰氯的反应以良好的收率轻松合成。在这些二硫化物与亲核试剂(胺和金属醇盐)的反应中,硫代羰基碳和硫基硫原子似乎都被亲核试剂攻击。通过用三苯基膦硫代羰基二硫化物脱硫,以高产率转化为相应的二硫酯。
