  arynes generated from 2-(trimethylsilyl)aryltriflates resulting in the transition-metal-free synthesis of N-H and N-aryl benzotriazoles has been demonstrated. Using CsF as the fluoride source in CH3CN, the N-H benzotriazoles are formed in high selectivity instead of the expected azidobenzene. Interestingly, N-aryl benzotriazoles are formed using KF and THF as solvent in an open-flask reaction. Moreover,

  已证明NaN3在[3 + 2]环合中作为叠氮化物组分的合成效用，该芳烃由2-（三甲基甲硅烷基）芳基三氟甲磺酸产生的芳烃导致无过渡金属合成NH和N-芳基苯并三唑。使用CsF作为CH3CN中的氟化物源，可以高选择性地生成NH苯并三唑，而不是预期的叠氮苯。有趣的是，在开瓶反应中使用KF和THF作为溶剂形成N-芳基苯并三唑。此外，还提出了苯并三唑的N1-芳基化的方法。
