Annulated cyanophenols are the products derived from the thermolysis of 3,6-diaryl-2,5-diazido-1,4-benzoquinones in the presence of an alkyne. The transformation is envisaged to involve the following steps: 1)thermal fragmentation of the azidoquinones to arylcyanoketenes, 2) cycloaddition of the ketenes to an alkyne to give 4-aryl-4-cyanocyclobutenones, 3) electrocyclic ring opening of the cyclobutenone
环状氰基苯酚是在炔烃存在下由3,6-二芳基-2,5-重氮基-1,4-苯醌热解衍生的产物。预期该转化包括以下步骤:1)将叠氮醌醌热裂解为芳基氰基酮,2)将烯酮环加成至炔烃上,得到4-芳基-4-氰基环丁烯酮,3)环丁烯酮的电环开环以产生( 2-芳基-2-氰基乙烯基)烯酮,和4)共轭烯酮的闭环,得到环状的氰基苯酚产物。类似地,从4-芳基-3-叠氮基-6-氯-5-乙氧基-1,2-苯醌的热解获得类似的产物。
