Abstract

We report a kinetic and spectroscopic analysis of alkynedependent chemoselectivity in the copper-catalyzed azide-alkyne click (CuAAC) reaction. Studies of six alkyne subtypes reveal that the rate-determining step (RDS) of an aromatic ynamine class is shifted from acetylide formation to the azide ligation/migratory insertion event allowing chemoselectivity independent of overall rate.
