Note 1.Azide-Alkyne Cycloadditions, a.k.a. “Click” chemistry. An interesting and useful application of organic azides that hasn’t yet made it into introductory organic chemistry textbooks (but likely will in the near future) is a process technically called the “copper-catalyzed azide-alkyne cycloaddition“, but more commonly just called the “alkyne-azide click reaction”.The rate of CuAAC is increased by a factor of 10 7 relative to the thermal process, 8 making it conveniently fast at and below room temperature. The reaction is not significantly affected by the steric and electronic properties of the groups attached to the azide and alkyne centers, and primary, secondary, and even tertiary, electron-deficient and electron-rich, aliphatic, aromatic, and ...
