Levenets Т.V., Listopad E.V., Kozminykh V.O. A NEW METHOD FOR OBTAINING HYDRAZONES 1-(3-QUINOXALON)ALKANDIONES-1,2The condensation of some ketones with diethyl oxalate followed by subsequent aryl diazonium chloride and 1,2-diaminobenzola is studied. Structure peculiarities of synthesized compounds on the basis of IR and NMR spectroscopy are discussed.Key words: multicomponent reactions, heterocyclic systems, hydrazones 1-(3-quinoxalon)alkandiones-1,2.
