Novel Modes of benzyne addition to 3,4-dimethyl-1,2,5-thiadiazole and 3,4-dimethyl-1,2,5-selenadiazole afford methyl derivatives of three heterocyclic systems: quinoxaline, 1,2-benzisothiazole, and 1,3-benzoselenazole respectively.
除3,4-二甲基-1,2,5-噻二唑和3,4-二甲基-1,2,5-硒代苯并恶唑外,苯并炔的新模式提供了三个杂环体系的甲基衍生物:喹喔啉,1,2-苯并噻唑和1,3-苯并硒唑。
