Phosphine generated from the red phosphorus in the system KOH-H2O-toluene adds regio- and chemoselectively to vinyl sulfides under radical initiation conditions with the formation of tris(2-organylthioethyl)phosphines, which are easily oxidized by elemental sulfur and selenium to the corresponding phosphine sulfides and phosphine selenides in 54–78% yield. The obtained adducts are split when treated
由KOH-H 2 O-甲苯体系中的红磷生成的膦在自由基引发条件下向区域性硫化物上进行区域选择性和化学选择性加成,生成三(2-有机基硫代乙基)膦,这些元素易于被元素硫和硒氧化成相应的磷化氢硫化物和硒化磷化氢,产率54-78%。当用酰胺钠的THF溶液处理时,将获得的加合物分开,得到三乙烯基膦和三乙烯基膦硫属元素化物。
