Abstract

The thermal Huisgen 1, 3-dipolar cycloaddition of organic azides and alkynes to build 1, 2, 3- triazoles usually requires elevated temperatures and provides a mixture of regioisomers.[1] The copper (I)-catalyzed azide–alkyne cycloaddition (CuAAC)[2] and ruthenium (II)- catalyzed azide–alkyne cycloaddition (RuAAC)[3] have been developed as powerful strategies for the regiospecific assembly of 1, 4-disubstituted 1, 2, 3-triazoles and 1, 5- ...
