A derivative of the novel heterocyclic ring system - 1,2,3,4-tetrahydro-1,4,6,2-oxadiazaphosphorine (1), was prepared by the cycloaddition of the nitrile oxide generated from hydroximoyl chloride (2) with aminomethylphosphonate (3). The structure was elucidated by NMR analysis and X-Ray crystallography. The stability of the new ring system was investigated.
