[2-(Arylmethylene)cyclopropyl]methyl}(phenyl)sulfanes and [2-(arylmethylene)cyclopropyl]methyl}(phenyl)selanes, generated in situ from 2-(arylmethylene)cyclopropylcarbinols with sodium benzenethiolate and sodium benzeneselenolate, could undergo rearrangement upon heating to afford (2-arylmethylidenebut-3-enyl)(phenyl)sulfanes and (2-arylmethylidenebut-3-enyl)(phenyl)selanes, in good to excellent
由2-(芳基亚甲基)环丙基甲醇与苯硫醇钠和苯硒基磺酸钠原位产生的[2-(芳基亚甲基)环丙基]甲基}(苯基)硫烷和[2-(芳基亚甲基)环丙基]甲基}(苯基)硒烷加热后进行重排,分别得到E-和Z-异构体的混合物,具有良好的收率(2-芳基亚甲基丁烯-3-丁烯基)(苯基)硫烷和(2-芳基亚甲基丁烯-3-丁烯基)(苯基)硒烷。在此过程的控制实验的基础上,提出了彻底的重排。
