An atom-economic green synthesis of tertiary phsophine sulfides has been developed based on catalyst- and solvent-free addition of secondary phosphine sulfides to diverse terminal and internal alkenes (hept-1-ene, cyclohexene, styrenes, allyl alcohol, vinyl ethers, vinyl sulfides, vinyltrimethylsilane, 1-vinylimidazoles, vinyl acetate). The reaction proceeds under mild conditions (80 °C, without solvent

The thioselenophosphinic acids, R2P(Se)SH (R = Ph, Cy, aralkyl), prepared by acidification of the sodium salts or generated in situ by reaction of secondary phosphine sulfides with elemental selenium, add easily to diverse vinyl sulfides and vinyl selenides in a Markovnikov manner to give the corresponding S- and Se-esters in a ∼60:40 molar ratio (83–96% total yield).

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
