The reaction between fluoroolefins 1 and 10e and benzenesulfenyl or selenenyl halides 6 is found to be solvent-dependent and gives in most cases predominantly the regioisomer 8.The structure of adducts 8 and 9 are ascertained by 1H, 19F and 77Se NMR spectroscopy. Compounds 8 are easily halogenated and treatment of the products with magnesium or zinc leads to the desired polyfluorovinyl Sulfides and
发现氟代烯烃1和10e与苯硫基或硒烯基卤化物6之间的反应是溶剂依赖性的,并且在大多数情况下主要给出区域异构体8。加合物8和9的结构通过1 H,19 F和77 Se NMR光谱确定。化合物8容易被卤化,并且用镁或锌处理产物产生所需的多氟乙烯基硫化物和硒化物10。这些试剂的第二种合成路线是由(氟乙烯基硫代衍生物11与苯硫基或亚硒基卤化物。烯烃10e也由三氟乙醛的硒缩醛8t获得。
