Spectral and Complex-Forming Properties of β-Bromo-Substituted Porphyrins in N,N-Dimethylformamide

摘要

Contributions of structural and electronic effects to the reactivity and chromophore properties of tetrapyrrole macrocycles modified by bromine atoms were revealed on the basis of the kinetic data on the complex formation of 2-bromo-5,10,15,20-tetraphenylporphyrin, 2,3,12,13-tetrabromo-5,10,15,20-tetraphenyl-porphyrin, and 2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetraphenylporphyrin with zinc(II) and copper(II) acetates in N,N-dimemylforrnamide, and also by measuring spectral characteristics of porphyrin ligands and zinc and copper porphyrinates.
