A smooth access to benzotriazoles via azide-benzyne cycloaddition
摘要:
A facile synthesis of 1-alkyl benzotriazoles is achieved through fluoride triggered azide-benzyne cycloaddition. Various alkyl azides were treated with 2-(trimethylsilyl) phenyl triflate in the presence of CsF in acetonitrile to afford the corresponding substituted benzotriazoles in good yield.

Herein, we describe a soluble iron(II)-phthalocyanine, [FeII(tBu4Pc)(py)2] (Pc = phthalocyaninato(2–)), as an effective catalyst in intramolecularC(sp3)–H bond amination, with alkyl azides as the nitrogen source, to afford the amination products in moderate to excellent yields with a broad substrate scope.
在此,我们描述了一种可溶性铁 ( II )-酞菁 [Fe II ( t Bu 4 Pc)(py) 2 ] (Pc = phthalocyaninato(2-)),作为分子内 C(sp 3 )-H的有效催化剂键胺化,以烷基叠氮化物为氮源,以中等至优异的产率提供胺化产物,底物范围广泛。
