Two new processes for the preparation of sec. phosphine sulfides which involve reaction of dialkylamino‐dialkyl or diaryl phosphines with hydrogen sulfide, and of dialkylthionophosphonates, (RO) 2 P(S)H, with G RIGNARD or organolithium reagents, respectively, are described. The addition of sec. phosphine sulfides to olefins and the condensation of sec. phosphine sulfides with N‐hydroxymethyldialkylamines are reported. The conversion of tert. Phosphine sulfides to the corresponding tert. phosphine oxides is readily achieved with hydrogen peroxyde. The physical properties of several new unsymmetrical tert. phosphine sulfide and oxides are listed.
