Complexes of Transition Metals with Petroleum Porphyrin Ligands: Preparation and Evaluation of Catalytic Ability

In the present work, first data on catalytic activity of d-metal complexes petroleum porphyrins obtained via two-stage re-metallization (acid demetallization with subsequent metalation) high-purity vanadyl are presented. During acid porphyrins, highest yield (49%) and spectral purity free petroporphyrin bases were achieved concentrated sulfuric a diluted solution in chloroform. series divalent cations Mn, Fe, Co, Ni, Cu, Zn, only last four metals complexed demetallated petroporphyrins without significant changes their component composition, whereas interaction Mn Fe causes an evident structural transformation or even full degradation macrocycles, respectively. The composition porphyrin-containing reactants products analyzed by FT-IR, UV-Vis, NMR, MALDI-TOF mass spectroscopic methods. petroporphyrin-based assayed reaction 2-mercaptoethanol oxidative dimerization, which copper exhibited activity.
