Selective redistribution reactions of tetraphosphorus hexaoxide; crystal structure of P4O6NC6H5

P4 O6 NR (R =–Ph, –C2H4Ph, –n-C6H13, –SO2Me, –CO2Et) are obtained from the reaction of tetraphosphorus hexaoxide with organic azides; the P4O5N cage-like structure is confirmed by 31P NMR spectroscopy and X-ray structure analysis of P4O6NC6H5.
