Abstract
A Cu/Pd transmetalation relay catalysis enables a three-component click reaction of azide, alkyne, and aryl halide to yield 1,4,5-trisubstituted 1,2,3-triazoles in one step in high yields with complete regioselectivity. This reaction offers an alternative to the well-established CuAAC click reactions only working on terminal alkynes.
