The mass spectra of several dibenzo ( d.f )‐1,3,2,‐dioxaphosphorepines of the typewhere X=0, S, Se and R=2,2′‐biphenylylene, have been studied. Dibenzochalcogen ions [RX] + ˙ stemming directly from [M] + ˙ were observed with high intensities, indicating specific migration of X from phosphorus to carbon with simultaneous destruction of the dioxaphosphorepine ring. Simple cleavage of PY as usually observed in similar organophosphorus compounds is not a common process here.
