investigated. When R = Me, mono-, non-geminal bis-, and tetrakis-dimethylamino-derivatives have been isolated, and the new ring compound (II), Me2N(S)[graphic omitted], obtained by reaction with 6 mol dimethylamine heated under reflux in chloroform solution. The analogous N-ethyl ring compound has been obtained from (I; R = Et). Attempts to synthesise the geminal bis(dimethylamino) derivatives, Cl2(S) P·NR·P(S)(NMe2)2

amines, [Cl2P(S)]2NR and Cl2PS·NR·PCl2(R = Me, Et, or Ph), have been prepared by reactions of the bis(dichlorophosphino)-amines, (Cl2P)2NR (R = Me, Et, or Ph), with elemental sulphur in the presence of anhydrous aluminium chloride. The compounds Cl2P(S)·NR·PCl2 eliminate PCl3 when heated leaving cyclodiphosphazanes, [R·NP(S)Cl]2. Dichlorophosphinothioyl(dichlorophosphinyl)amines, Cl2P(S)·NR·P(O)Cl2(R
