When I use the "Convert Structure to Name" feature in ChemDraw Professional 16.0 for diphenylphosphoryl azide (the proper name), I instead get diphenylphosphinyl azide as the structure. (when I use "Convert Structure to Name," it names the created structure as diphenylphosphinyl azide-correctly). DPPA is commonly used to intruduce azides in Mitsunobu reactions and is not a rare or incorrect name
Other sources (Wikipedia) also had similar errors (which I have corrected).
It interprets "Diphenyl Phosphorazidate" correctly, but this term has half as common (according to Google search results)
