Abstract
Tris-dibenzoylmethanate ([V(dbm)3 ]) and tris-benzoylacetonate vanadium ([V(bac)3 ]) were obtained by electrochemical synthesis. The composition of chelates was determined using elemental analysis and IR spectral data. It was shown that the formation of a quasi-aromatic metallocycle, the main structural element of chelate, occurred as a result of electrolysis. At the same time, the batachromic shift of absorption bands of carbonyl groups was more than 100 cm–1. The overwhelming majority of absorption bands in the IR spectra of both compounds had mixed nature. For ([V(dbm)3 ] the characteristic of absorption bands did not exceed 13.5 %, and for [V(bac)3 ] – 10.3 %. The peripheral groups of ligands (phenyl and methyl) did not undergo transformation when influenced by electric current.
