Реферат: A 4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazole-3-oxide-1-oxyl lithium derivative was found to react with 5,6,7,8-tetrafluoro- or 5,7,8-trifluoro-6-(trifluoromethyl)quinoline-N-oxides with the formation of products of aromatic nucleophilic substitution of the H atom at position 2 of the quinoline ring. The reaction regioselectivity is supported by the data of quantum-chemical calculations. Molecular and crystal structures of the obtained nitronyl nitroxides were solved by monocrystal X-ray diffraction analysis, and the nature of the radical was ascertained by electron spin resonance spectroscopy. Heterospin complexes of Cu(hfac)2 with the synthesized quinoline-substituted nitronyl nitroxides were prepared. According to X-ray diffraction analysis, seven-membered metallocycles are formed in the complexes owing to simultaneous coordination of the nitroxyl and N-oxide groups by the Cu atom. © 2020 Elsevier B.V.
