Some chemistry of a new class of compounds, (phosphinomethyl)phosphine sulfides, Ph2P(S)CH2PR1R2, is described. Reaction with sulfur gives disulfides, Ph2P(S)CH2P(S)R1R2, with sodium gives unsymmetrical di(tertiary phosphines), Ph2PCH2PR1R2, with alkyl halides gives phosphonium salts, [Ph2P(S)CH2PR1R2R3]X, and with group 6 metal carbonyls gives a complex with phosphorus and sulfur bonded to the metal in a five-membered chelate ring, [Ph2P(S)CH2PR1R2]M(CO)4; heating causes the sulfur to transfer to the more basic phosphorus atom, producing Ph2PCH2P(S)R1R2. Extensive phosphorus and proton NMR data are given.
