Mono- and dihydrazones, the structure of which were established by means of 1H and 13C NMR, IR, and electronic absorption spectroscopy, were synthesized by reaction of 3-chloro-2-hydrazino- and 2,3-dihydrazinoquinoxalines with 1H-indole-2,3-dione and its 1-methyl and 1-butyl homologs.Thermal and photochemical conversion of the E, Z isomer to the Z isomer is observed, while the reverse transformation is observed in the case of treatment with alkali.
