STUDY OF CADMIUM OCTA(4-METHOXYPHENYL)PORPHYRINATE IN REACTION OF METAL EXCHANGE WITH TIN CHLORIDE IN DMF

Metal-exchange reaction for complexes with macrocyclic ligands refers to a special type of complex coordination interactions. The reaction of metal exchange has founded wide application for the synthesis of complexes of natural and synthetic porphyrins. In the general form, the metal-exchange reaction may be written as follows:
MР + M/Xn(Solv)m-n M/Р + MXn(Solv)m-n

SPECTRAL CHARACTERISTICS OF CONFORMATION ISOMERS OF MESO-OCTAMETHYL-CALIX(4)PYRROLE BASED ON QUANTUM-CHEMICAL CALCULATIONS

The structure optimization and calculation of electronic absorption spectra of meso-octa-methylcalix(4)pyrrole conformers was performed by density- functional theory using hybrid B3LYP functional in cc-pVTZ basis set of Gaussian 09 package. Analysis of experimental UV-Vis spectra of solutions of calix(4)pyrrole was carried out in various solvents. The conclusion on the existence of a dynamic equilibrium between conformers in solutions of meso-octamethylcalix(4)pyrrole was made.

Key words: calix(4)pyrrole, conformational analysis, solutions, supramolecular interactions
