    • Abstract


      A series of the title compounds have been prepared and the structures assigned to them were confirmed by IR and mass spectra. The existence of hydrogen bonding between the amidic hydrogens and the phosphoryl oxygen in these compounds is indicated by theIR spectra. The benzodiazaphosphole ring system appears to be quite stable under electron impact. An interesting type of McLafferty rearrangement occurred in many of these molecules resulting in the formation of ions of benzodiazaphosphinous acid along with the ejection of cyclo-hexane moiety from the molecular ion. Cleavage of P-N bonds of the molecular ions leading to the formation of theo-phenylene diamine cations is observed
