Abstract The reaction of 3-benzylidenephthalimidine (3-BPI) with zinc benzoate as a chelating agent has led to the only tetramerization of 3-BPI to yield meso -tetraphenyltetrabenzoporphinato zinc (ZnTPTBP), while the use of zinc acetate has provided a complicated mixture of ZnTBPs with meso -phenyl substituent(s), the number of which is from one to four. From the FD-MS data and 3D(dimensional)-HPLC analysis, it is shown that this reaction product is contaminated with the benzyl adducts of ZnTPBP. This benzyl fragmentation probably occurs by the high temperature pyrolysis of 3-BPI.
