with Cl2P·NMe·P(S)Cl2. Similar reactions of Cl2(O)P·CH2·P(O)Cl2 with NH2But and NH2Pri give a new class of ring compound, Cl(O)[graphic omitted]R (R = Pri or But)(1,2,4-azadiphosphetans), but no cyclic products have been identified from analogous reactions with Cl2(O)P· CH2·CH2·P(O)Cl2. Attempted cyclisation of (Me2N)Cl(O)P-CH2-P(O)Cl(NMe2) by NH2But gives an acyclic product. (ButHN)(Me2N)(O)P·CH2·P(O)(NMe2)(NHBut)

Bis(dichlorophosphinyl)methylamine, [Cl2P(:O)]2NMe, has been prepared by the reaction of phosphoryl(V) chloride with dichlorophosphinylmethylamine, Cl2P(:O)·NHMe, and with heptamethyldisilazane, (Me3Si)2NMe. The former reaction has been extended to prepare the analogous monophenyl derivative, Cl2P(:O)·NMe·P(:O)ClPh, and reactions involving heptamethyldisilazane were adapted to give the dichlorophosphinyl
