Abstract

Reactions of complex formation of 5,10,15,20-tetraphenylporphine (H2TPP) and tetra-tert-butylphthalocyanine (H2(t-Bu)4Pc) with adenine and adenosine complexes of d-metals in DMSO and ethanol are studied. It was found that H2TPP reacts with Cu(II) and Hg(II) adeninates and adenosinates in DMSO, but does not react with Zn(II), Co(II), and Cd(II) adeninates and adenosinates (with both bridging and monodentate type of the ligand coordination). H2(t-Bu)4Pc enters the complex formation reaction with adeninates and adenosinates of all studied metals in DMSO at almost equal rates. The states of adenine and adenosine complexes of different d-metals in DMSO and ethanol are proposed on the basis of kinetic data obtained.
