Straightforward Solvent-Free Synthesis of Tertiary Phosphine Chalcogenides from Secondary Phosphines, Electron-Rich Alkenes, and Elemental Sulfur or Selenium

A series of tertiary phosphine sulfides and selenides have been synthesized in excellent yields (88-99%) via a three-component reaction between secondary phosphines, electron-rich alkenes (styrene, vinyl chalcogenides), and elemental sulfur or selenium, proceeding under solvent-free conditions (80-82C, 4-44 h). The interaction occurs via initial oxidation of secondary phosphines with elemental sulfur or selenium followed by noncatalyzed anti-Markovnikov addition of the generated R2P(E)H (E = S, Se) species to alkenes to afford the corresponding adducts with high chemo- and regioselectivity.

One-pot microwave synthesis of tertiary phosphine sulfides directly from aromatic alkenes, elemental phosphorus and sulfur in KOH-DMSO system

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- tBu-phenyl)ethyl]- and tris[2-(4-Cl-phenyl)ethyl]phosphine sulfides in 53%, 38% and 42% yield, respectively.
