The structural characteristics of 5-aryl-3-(arylhydrazono)furan-2(3Н)-ones accessed via azocoupling of furan-2(3Н)-ones with aryldiazonium salts were established by NMR spectroscopy (including two-dimensional NMR experiments 1H–13C HMQC, 1H–15N HMQC, 1H–13C HMBC, NOE) and X-ray structural analysis techniques. The reaction of synthesized compounds with hydrazine leading to the formation of six-membered heterocycles, hydrazono-substituted 4,5-dihydropyridazin-3(2Н)-ones, was studied.
