摘要

3- 羟基-2,5-二叔丁基-1,4-苯醌与苯肼盐酸盐的反应主要导致位置 1 上相应的腙与 3,6-二叔丁基-4-(苯基-偶氮基)邻苯二酚发生同分异构。核磁共振光谱评估了同分异构的热力学参数。通过 XRD 研究确认了腙结构。

4-Phenyldiazenyl-substituted 3,6-di-tert-butylcatechol: synthesis and azo–hydrazone equilibrium

Reaction of 3-hydroxy-2,5-di-tert-butyl-1,4-benzoquinone with phenylhydrazine hydrochloride mainly leads to the corresponding hydrazone at the position 1 existing in tautomeric equilibrium with 3,6-di-tert-butyl-4-(phenyl- diazenyl)catechol. Thermodynamic parameters of the tautomerization were evaluated by NMR spectroscopy. The hydrazone structure was confirmed by XRD study.
