Veratrole reacts with 1,4-benzoquinone in the presence of aluminium chloride to form 10,11-dimethoxytriphenylene-1,4:5,8-diquinone. Related products result when 2-chloro- and 2,3-dichloro-1,4-benzoquinone are used. 3,4-Dimethoxyphenyl-1,4-benzoquinone reacts in a similar manner with unsubstituted, 2-methyl-, 2-chloro-, and 2,3-dichloro-1,4-benzoquinone, and with itself. The structures of the diquinones
Veratrole在氯化铝的存在下与1,4-苯醌反应形成10,11-二甲氧基三亚苯基-1,4:5,8-二醌。当使用2-氯-和2,3-二氯-1,4-苯醌时,会产生相关的产物。3,4-二甲氧基苯基-1,4-苯醌与未取代的2-甲基-,2-氯-和2,3-二氯-1,4-苯醌以类似的方式反应,并与其自身反应。二醌的结构来自其光谱性质,以及它们通过还原性乙酰化转化为相应的三亚苯基-1,4,5,8-四乙酸四苯酯的过程。
