Benzynes can be generated by the intramolecular thermal cycloisomerization of triynes-the title HDDA reaction. We report here that these can be trapped by cycloaddition reaction with trimethylsilyl azide (1,3-dipolar) or a furan or pyrrole (4+2 Diels-Alder).
苯炔可通过三炔的分子内热环异构化反应生成——即标题中的HDDA反应。我们在此报告,这些苯炔可通过与叠氮基三甲基硅烷(1,3-偶极体)或呋喃或吡咯(4+2狄尔斯-阿尔德反应)的环加成反应捕获。
