The mass spectra of several ms‐porphyrins and their metalloderivatives have been obtained on an AEI MS‐902 mass spectrometer. The main features of these spectra are very stable parent peaks and relatively abundant doubly‐charged and triply‐charged fragments. Metal substitution has a drastic effect on the fragmentation pattern, which discloses formation of fragments with a stable composite π‐electron ring, including Hückel rings. Ion‐molecule reactions giving products up to [M + 124] + are also reported.
