ABSTRACT

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 (80-82°C, 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.
