series of tertiary phosphine sulfides and selenides have been synthesized in excellent yields (88-99%) via a three-component reaction between secondaryphosphines, electron-rich alkenes (styrene, vinyl chalcogenides), and elemental sulfur or selenium, proceeding under solvent-free conditions (80-82°C, 4–44 h). The interaction occurs via initial oxidation of secondaryphosphines with elemental sulfur
通过仲膦、富电子烯烃(苯乙烯、乙烯基硫属化物)和元素硫或硒之间的三组分反应,在溶剂下进行,合成了一系列叔膦硫化物和硒化物,收率极好(88-99%)无条件(80-82°C,4-44 小时)。相互作用是通过二级膦与元素硫或硒的初始氧化,然后将生成的 R2P(E)H (E = S, Se) 非催化反马尔可夫尼科夫加成到烯烃中,以提供相应的具有高化学和区域选择性的加合物.

Aromatic alkenes (vinylbenzene, 1-(tert-butyl)-4-vinylbenzene, 1-chloro-4-vinylbenzene) react with red phosphorus and elemental sulfur in the superbasic system KOH-DMSO(H2O) under microwave irradiation (600 W, 6-8 min, Ar) in the presence of hydroquinone to afford tris(2-phenylethyl)-, tris[2-(4-Bu-t-phenyl)ethyl]- and tris[2-(4-Cl-phenyl)ethyl]phosphine sulfides in 53%, 38% and 42% yield, respectively.[GRAPHICS].
