- Abstract
The direct synthesis of symmetrically substituted porphyrins: 2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetra(3,5-dibromophenyl) porphyrin and 2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetra(3,4,5-trimethoxyphenyl) porphyrin – was proposed. The obtained compounds were identified by electron absorption, 1H NMR spectroscopy and mass spectrometry. The acid-base and coordination properties of 2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetra(3,5-dibromophenyl) porphine and 2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetra(3,4,5-trimethoxyphenyl) porphine with respect to Zn2+ and Pd2+ ions in acetonitrile at 298–328 K were studied. The effect of substituents in the β-positions and meso-phenyl fragments of the macrocycle on the spectral and coordination properties of the analyzed compounds was revealed. β-Unsubstituted analogs studied earlier were used as objects of comparison.
