Phosphine readily adds to 1-(tert-butyl)-4-vinylbenzene in the KOH-DMSO system (70-120 °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.

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.
A one-pot synthesis of a branched tertiary phosphine oxide from red phosphorus and 1-(tert-butyl)-4-vinylbenzene in KOH-DMSO: an unusually facile addition of P-centered nucleophiles to a weakly electrophilic double bond

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.
