Synthesis of β-Bromo-Substituted Cu(II) Tetraphenylporphyrinates

Resumo

Bromination reactions of Cu(II) 5,10,15,20-tetraphenylporphyrinate with N-bromosuccinimide in chloroform and chloroform–dimethylformamide mixture and complexation of 2-bromo-5,10,15,20-tetraphenylporphyrin and 2,3,12,13-tetrabromo-5,10,15,20-tetraphenylporphyrin with copper(II) acetate in dimethylformamide have been studied. Mono-, tetra-, and octabromo-substituted Cu(II) porphyrinates have been synthesized. Obtained compounds have been identified by electronic absorption spectroscopy, IR spectroscopy, mass spectrometry, and elemental analysis.
