An efficient and highly versatile method for the synthesis of diverse regiospecific 1-arylbenzotriazoles being important medicinal scaffolds, by the copper (1) catalysed intramolecular N-arylation of diazoaminobenzenes of 2-haloaryldiazonium salts in PEG-water has been developed. A very simple reaction protocol, large number of substrate affordability and excellent yields are the main features of this methodology.

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.

(Chemical Equation Presented) A variety of substituted benzotriazoles have been prepared by the [3 + 2] cycloaddition of azides to benzynes. The reaction scope is quite general, affording a rapid and easy entry to substituted, functionalized benzotriazoles under mild conditions.
