Reaction direction of N-sulfonyl derivatives of 1,4-benzoquinone monoimine with substituted hydrazines depends on the redox potential of the quinone imine and on the basicity of the hydrazine. Aryl (alkyl)hydrazines of high basicity favor the reduction of quinone monoimine. In reactions with less basic aroylhydrazones N'-(4-oxocyclohexa-2,5-dienylidene)aroylhydrazides were obtained only from the alkylsubstituted
1,4-苯醌单亚胺的N-磺酰基衍生物与取代的肼的反应方向取决于醌亚胺的氧化还原电势和肼的碱性。高碱性的芳基(烷基)肼有助于减少醌单亚胺。在与碱性较低的芳酰基hydr的反应中,仅从具有较低氧化还原电势的N-磺酰基衍生物的喹啉环中取代的烷基获得N ′-(4-氧代环己二-2,5-二烯基)芳酰基酰肼。
