摘要：

1,1,3,3-Tetrakis(dimethylamino)-1-lambda-5,3-lambda-5-diphosphete, 1, reacts with aniline to give by opening of the ring 2,2,4,4-tetrakis(dimethylamino)-1-phenyl-1,2-lambda-5,4-lambda-5-azadiphosphapenta-1,3-diene, 2, with p-CN - C6F4 - NH2 the product is 1-(4-cyano-2,3,5,6-tetrafluorophenyl)-2,2,4,4-tetrakis(dimethylamino)-1,2-lambda-5,4-lambda-5-azadiphosphapenta-1,3-diene, 3. t-Butylamine or diethylamine do not react with 1. Mesitylphosphane opens the ring system 1 forming by reduction of one phosphorus atom {[bis(dimethylamino)phosphanyl]methylidene}bis(dimethylamino)methylphosphorane, 4. The same product 4 is obtained by reaction with phenylphosphane. The reaction products 2 - 4 are characterized by their nmr, mass, and ir spectra. Their way of formation is discussed. In 4 a 5J(PH), in 3 a 7J(CF) long range coupling constant could be identified.
