Red phosphorus reacts with 1-(tert-butyl)-4-vinylbenzene in a superbase media (KOH–DMSO, 90–100 °C, 3 h) to give tris[4-(tert-butyl)phenethyl]phosphine oxide in 77% yield. Microwave activation of the reaction affords the phosphine oxide in 82% yield in 6 min.

Phosphine readily adds to 1-(tert-butyl)-4-vinylbenzene in the KOH-DMSO system (70-120 degrees C, 3 h, atmospheric pressure) to form bis[4-(tert-butyl)phenethyl]phosphine and tris[4-(tert-butyl)phenethyl]phosphine, which are further oxidized to corresponding phosphine oxides, sulfides and selenides.

Secondaryphosphine oxides react with vinyl sulfides (both alkyl- and aryl-substituted sulfides) under aerobic and solvent-free conditions (80 degrees C, air, 7-30 h) to afford 1-hydroxy-2-(organosulfanyl)ethyl(diorganyl)phosphine oxides in 70-93% yields.
