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)2P(S)H, with GRIGNARD or organolithium reagents, respectively, are described. The addition of sec. phosphine sulfides to olefins and the condensation of sec. phosphine sulfides with N-hydroxymethyldialkylamines

The coupling reaction of diphenylphosphine sulfide with N,N-disubstituted formamides in the presence of an excess amount of sodium hydride proceeded smoothly to give the corresponding aminomethyldiphenylphosphine sulfides in good yields. This method is expected to provide a useful synthesis of P,N-containing ligands.
