Abstract
α-(6-Methyl-2-benzothiazolyl)-α-phenyl-β-(2,6-dinitrophenyl)hydrazyl and α-(2-methyl-6-benzothiazolyl)-α-phenyl-β-(2,6-dinitrophenyl)hydrazyl and their corresponding hydrazines were synthesized. The properties of the compounds obtained were investigated by IR, UV, and visible spectroscopy. Their complexing ability was studied by an optical method and from their electrical conductivity. The ESR spectra of the radicals were recorded. The limiting currents and reduction potentials of the hydrazines on a dropping mercury electrode were found. The charge and spin densities of the compounds were calculated by means of the Hückel MO and MacLachlan methods. It was demonstrated that the hydrazines form unstable charge-transfer complexes in benzene—piperidine solutions; the characteristics of these complexes depend on the structure of the RR′N-NH-hydrazine residue.
