Oxidation of vinylthio(halo)pyridines with 30–33% hydrogen peroxide solution in acetic anhydride at 20–25°C furnished vinylsulfonyl(halo)pyridines. Nucleophilic addition reactions of 2-amino-1-ethanethio hydrochloride and thiosemicarbazide to the multiple bonds of vinylsulfonyl(halo)pyridines were performed.
在 20-25°C 的温度下,用 30-33% 的过氧化氢乙酸酐溶液氧化乙烯基硫代(卤代)吡啶,生成了乙烯基磺酰基(卤代)吡啶。2-amino-1-ethanethio hydrochloride 和 thiosemicarbazide 与乙烯砜基(卤代)吡啶的多键发生了亲核加成反应。
