Phosphoric carboxylic imides. Part 6. Structure and reactivity of 1,3,2-diazaphospholidine-4,5-diones; crystal structure of 1,3-dimethyl-2-methylamino-1,3,2-diazaphospholidine-2,4,5-trione

1,3-Dimethyl-2-methylamino-1,3,2-diazaphospholidine-2,4,5-trione (1b) has been synthesized, and its solvolytic behaviour and X-ray crystalstructure determined. Methanolysis of (1b) gives products of the cleavage of both imide P–N bonds, indicating that the ring opening in (1b) is much slower than the second P–N cleavage in the ring-opened intermediate. The low reactivity of (1b) is correlated with

dichlorophosphino(dichlorophosphinyl)methylamine, Cl2P·NMe·P(O) Cl2 by dimethylaminotrimethylsilane and methoxytrimethylsilane respectively initially occurs at the tervalent phosphorus atom. The mono-dimethylamino-derivative Cl(Me2N)P·NMe·P(O)Cl2, rearranges to its isomer, Cl2P·NMe·P(O)ClNMe2 at ambient temperatures. Further dimethylaminolysis gives the bisdimethylaminoderivative, Cl2P·NMe·P(O)(NMe2)2 which
