Abstract Two polymorphs of 2,5-bis(cyclohexylamino)-1,4-benzoquinone (BCBQI&BCBQII) are synthesized by an efficient alternate method which includes the oxidation of an aromatic aldehyde to benzoquinone moiety followed by its nucleophilic substitution in a single pot. The synthesized polymorphs have been characterized and distinguished by spectral and single crystal X-ray diffraction methods. A possible mechanism for the conversion is also suggested.

摘要 2,5-双（环己基氨基）-1,4-苯醌的两种多晶型物（BCBQI&BCBQII）是通过一种有效的替代方法合成的，该方法包括将芳香醛氧化为苯醌部分，然后在一个锅中进行亲核取代。合成的多晶型物已通过光谱和单晶 X 射线衍射方法进行表征和区分。还建议了一种可能的转换机制。
