Abstract
The interaction of Co(II)- and Co(III)-5,10,15,20-tetraphenylporphyrins with tert-butylhydroxyperoxide and di-tert-butylhydroxyperoxide in benzene at 298 K were studied by spectrophotometry and 1H NMR spectroscopy. Kinetic parameters of the destruction reactions of porphyrin macrocycle depending on the nature of peroxide the valence of cobalt cation, and the presence and nature of axial ligands were calculated. Products of consecutive decomposition of tetrapyrrole macrocycle to monopyrroles were determined by mass spectrometry.
