The reaction of benzyne, generated from anthranilic acid, benzothiadiazole 1,1-dioxide, and diphenyliodonium-2-carboxylate, with cinnamaldehyde results in the formation of flav-3-ene. Similarly tetrachlorobenzyne, generated from tetrachloroanthranilic acid, tetrachlorobenzenediazonium-2-carboxylate hydrochloride, and 3,4,5,6-tetra-chloro-2-(3,3-dimethyltriazeno)benzoic acid, affords 5,6,7,8-tetrachloroflav-3-ene
由邻氨基苯甲酸,苯并噻二唑1,1-二氧化物和-2-羧酸二苯基碘鎓生成的苯并with与肉桂醛的反应导致形成flav-3-ene。类似地,由四氯邻氨基苯甲酸,四氯苯重氮-2-羧酸盐酸盐和3,4,5,6-四氯-2-(3,3-二甲基三叠氮基)苯甲酸生成四氯苯并生成5,6,7,8-四氯黄酮-3-烯。与其他αβ-不饱和醛的反应导致形成2 H-色烯的衍生物。已使用14 C,2 H和烷基作为标记物研究了反应机理。
