Benzyne Click Chemistry with in Situ Generated Aromatic Azides
摘要:
An efficient synthesis of substituted benzotriazoles using an azide-alkyne 1,3-dipolar cycloaddition "click reaction" is described. Key to the procedure is the in situ generation of the reactive aromatic azide and benzyne reaction partners.

Arene substitution patterns are well-known to affect the regioselectivity of a given transformation but not necessarily the type of reactivity. Herein, we report that the substitution pattern of alkoxyarenes dictates whether a putative one-electron or two-electron reaction predominates in reactions with Selectfluor. A series of amination products is presented, resulting from the single-electron oxidation
