The fractional distillation of 0-(2-alkenyl or 2-cycloalkenyl) S-alkyl dithiocarbonates (xanthates) affords 2-alkenyl or 2-cycloalkenyl alkyl sulfides. The reaction involves the [3,3]-sigmatropic rearrangement of the xanthates to produce S-(2-alkenyl or 2-cycloalkenyl) S-alkyl dithiocarbonates followed by extrusion of carbon oxysulfide to give 2-alkenyl or 2-cycloalkenyl alkyl sulfides.
0-(2-烯基或2-环烯基)S-烷基二硫代碳酸酯(黄原酸酯)的分馏得到2-烯基或2-环烯基烷基硫化物。该反应涉及黄原酸酯的[3,3]-σ重排,以产生S-(2-烯基或2-环烯基)S-烷基二硫代碳酸酯,随后挤出氧硫化碳,得到2-烯基或2-环烯基烷基硫化物。
