Fragmentation and rearrangement processes in the mass spectra of perfluoroaromatic compounds. Part XI. Heterocyclic derivatives of phosphorus and some transition metals

The mass spectra of a number of phospholes and metalloles of general structure 1 and 2 arediscussed with respect to their fragmentation and ion rearrangement processes. Of special interest is the migration of ring fluorines to the central atom during fragmentation. The bonding principles involved for the postulated intermediates are discussed.
