Micellar media in water provide a simple and efficient environment favoring the multi-component synthesis of 1,2,3-triazoles from organic bromides, sodium azide and terminal alkynes in the presence of [Cu(IMes)Cl] 1 catalyst at room temperature within a few hours.

of 1-allylated and 1-benzylated 1,2,3-triazoles with varying substituents at the 4-position were prepared in yields ranging from 74-98% using a two-step one-pot click transformation. This tandem reaction involved the nucleophilic substitution of allyl chloride and benzyl bromide with sodium azide to form organic azide intermediates followed by Cu-catalyzed Huisgen 1,3-dipolar cycloaddition with alkyne
