| Abstract: | (5,15-Bis(2-thienyl)-and 5,15-diphenyl-3,7,13,17-tetramethyl-2,8,12,18-tetra-n-butyl-21H,23H-porphinato)copper(II) complexes were synthesized and the basicity, absorption spectra (UV-Vis, IR, 1H NMR) of the macrocyclic ligands and the stability of the complexes in AcOH-H2SO4 mixed solvents were studied with the aim to reveal the effect of 2-thienyl substituent on the properties of substituted porphyrins. Data on kinetics were obtained, reaction mechanism of complex dissociation was reasoned, and the effect of functional substitution on the properties of macrocyclic bases and their complexes with copper(II) were determined. |
