The fragmentation behavior of N‐phenyliminotriphenylphosphorane has been studied by examining the mass spectra of the title compound and eight of its substituent‐labeled derivatives. These compounds were found to be quite stable to electron‐impact, exhibiting strong molecular ions (base peak) and little fragmentation. The majority of the cleavage products are analogous to those observed with triphenylphosphonium ylids, the [M – H] fragment ion being usually very intense.
