Abstract 5-[2-(Perfluoroalkyl)ethylthio]methyl}-1,3,4-oxadiazole-2-thiones 4a, b and 4-amino-5-[2-(perfluoroalkyl)ethylthio]methyl}-4H-1,2,4-triazole-3-thiones 5a, b have been prepared from 2-(perfluoroalkyl)ethane thiols 1a, b through a multistep reaction sequence. Compounds 4a, b were further reacted with aryloxysulfonylisocyanates to give the corresponding 5-[2-(perfluoroalkyl)ethylthio]meth
摘要 5-[2-(全氟烷基)乙硫基]甲基}-1,3,4-恶二唑-2-硫酮 4a, b 和 4-氨基-5-[2-(全氟烷基)乙硫基]甲基}-4H- 1,2,4-三唑-3-硫酮5a、b已通过多步反应序列从2-(全氟烷基)乙硫醇1a、b制备。化合物4a、b进一步与芳氧基磺酰基异氰酸酯反应得到相应的5-[2-(全氟烷基)乙硫基]甲基}-N-(芳氧基磺酰基)-2-硫代-1,3,4-恶二唑-3(2H)-羧酰胺 6a-d。新产品以良好到中等的收率获得,其结构是根据红外、核磁共振和质谱数据确定的。
