Interaction of Imidazole Derivatives with Electron Acceptors. II. Reaction Products of Imidazole with p-Benzoquinone

Abstract

The interaction between imidazole and p-benzoquinone in acetonitrile was investigated at both low temperature (below 0°) and room temperature. The step of formation of the charge-transfer complex between two intact molecules could not be detected. Instead, the two compounds were found to react with each other fairly quickly at room temperature to form 2, 5-bis (imidazol-1-yl) hydroquinone, 2, 3-bis (imidazol-1-yl) hydroquinone and hydroquinone.
