Abstract 1-(Phenylthio)cyclopropylcarbinyl alcohols are converted to 2-alkyl-1, 1-di(phenylthio)cyclobutane derivatives upon treatment with 48% HBr and ZnBr2. Heating with copper triflate and Hunig's base gave 2-alkyl-1-(phenylthio)cyclobutenes which were pyrolyzed to 3-alkyl-2-di-(phenylthio)-1,3-butadienes in moderate to good yield.
摘要 1-(苯硫基) 环丙基甲醇在用 48% HBr 和 ZnBr2 处理后转化为 2-烷基-1, 1-二(苯硫基) 环丁烷衍生物。用三氟甲磺酸铜和 Hunig 碱加热得到 2-烷基-1-(苯硫基)环丁烯,其以中等至良好的产率热解为 3-烷基-2-二-(苯硫基)-1,3-丁二烯。
