A procedure was developed for preparing 4,5; 7,8-dibenzo-1,3,2-diazaphosphocanes containing trivalent and pentavalent phosphorus atoms. The structure of the compounds was determined by NMR spectroscopy and single crystal X-ray diffraction. The conformational transitions of the diazaphosphocanes in solution were analyzed. First data were obtained on transformations of the obtained eight-membered heterocycles.
