N-bromosuccinimide and N-chlorosuccinimide, respectively, in a mixture of chloroform with methanol. Treatment of the halogenated zinc porphyrins with trifluoroacetic acid in chloroform gave the corresponding free ligands. The isolated compounds were identified by electronic absorption, 1H NMR, and mass spectra. The acid–base properties of 5,10,15,20-tetrakis(2,6-dichlorophenyl)porphyrin, 2,3,7,8,12,13,17,18-octabromo-5
