A Stepwise Huisgen Cycloaddition Process: Copper(I)-Catalyzed Regioselective “Ligation” of Azides and Terminal Alkynes

By simply stirring in water, organic azides and terminal alkynes are readily and cleanly converted into 1, 4-disubstituted 1, 2, 3-triazoles through a highly efficient and regioselective copper (I) -catalyzed process (see scheme for an example).
