Secondary phosphine oxides and phosphine sulfides react with acetylene, methylacetylene, and phenylacetylene in the presence of strong bases (KOH-DMSO, KOH-THF) by the mechanism of double nucleophilic α,β-addition to form tertiary diphosphine dioxides and diphosphine disulfides in high yield (up to 97%).

Secondaryphosphinesulfides react with acetylene and methylacetylene in the system KOH—DMSO (50 °C, 2—3 h) to form the corresponding tertiary bis-phosphine sulfides in high yield (up to 97%). Specific features of the NMR spectra (1H, 13C, and 31P) of compounds obtained are discussed.
