Green click synthesis of β-hydroxy-1,2,3-triazoles in water in the presence of a Cu(<scp>ii</scp>)–azide catalyst: a new function for Cu(<scp>ii</scp>)–azide complexes

Abstract

A new method for preparing 1,2,3-triazols<italic>via</italic>a [3+2]-cycloaddition reaction is introduced. The effect of reaction temperature on the epoxide ring opening reactions is also investigated.
