Abstract From the fragmentation behavior of alkyl substituted porphyrins and phthalocyanines and their metal complexes it can be seen that in contrast to, e.g., acetylacetonates or oxinates in most cases the complexed metal ion does not influence the fragment formation since ionisation occurs by removal of an electron from a ring orbital. Exceptions are porphyrin complexes of Mn2+ and Fe2+ where apparently a metal-3d-orbital is involved. The danger of misinterpretation regarding the loss of even electron fragments actually caused by pyrolytic processes is pointed out.
