Способ ПО п. 1, отличаю - щ и и с   тем, что нагревание ведучдо .This invention relates to phosphorus chemistry, namely to a new method of producing six-membered heterocyclic phosphorus derivatives containing P-N P systems with a four-coordinated phosphorus atom in a cycle of the general formula 7 (t, in CHO, where R is alkyl; R is hydrogen or alkyl; X is oxygen or sulfur; y is alkyl or alkoxy. A known method for producing N-phosphorylated 1,3,2-oxazaphospholanes or phosphodinans containing the P -N system is in a heterocyclic ring. These compounds can be obtained by reaction or oxalic amides phosphorus or phosphonic L: acids with complete phosphorous amides or tetraalkyl diamides of alkyl (aryl) -phosphonic acids when heated. However, the compounds of this formula have not been described until now, and their preparation is not known. The method of preparation of N-phosphorylated 1,3, 2-oxazaphosphorinanes are such that 2-alkyl- (alkoxy) -2-oxo (thio) -1, 3,2-oxazaphosphorinanes are reacted with equimolecular amounts of hexaalkyltriaminophosphines. In this case, re-amidation unexpectedly proceeds to form the target products. Synthesis is carried out without solvent with distillation of dialkylamine at 120-160 ° or in a solvent at boiling. The outputs of the products are 55-75%. The structure of the obtained products was confirmed by the data of elementary analysis, IR, NMR and spectroscopy. In the NMR spectra of compounds, there are two doublets of equal intensity. The doublet nature is due to the spin-spin interaction of two phosphorus atoms, which are different coordination sites in the P - | system. moreover, the constant is much larger for thione derivatives.
