  Halogenation of N-substituted para-quinone monoimine and para-quinone monooxime esters: V. Chlorination and bromination of N-arylsulfonyl-1,4-benzoquinone monoimines dialkyl-substituted in the quinoid ring

  摘要：

  The direction of halogen addition to N-arylsulfonyl-1,4-benzoquinone monoimines dialkyl-substituted in the quinoid ring is governed by the steric factors: the size and position of the substituent, the halogen volume, and the position of the substituent at the nitrogen. The first stage of halogenation of N-arylsulfonyl-4-aminophenols with two alkyl substituents in the phenylsulfonyl ring largely occurs as electrophilic substitution.

  1,4-苯醌单亚胺的N-磺酰基衍生物与取代肼的反应

  摘要：

  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。

  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
