摘要
Summary The article herein briefly introduces the story of the birth of click chemistry and its evolution after that.A new angle to interpret click reac-tions was proposed using the"reactivity availability-functionality"trilogy.CuAAC(Copper-catalyzed azide-alkyne cycloaddition),the most popular click reaction by far,was revisited along with the thiol-ene,metal-free AAC,SuFEx(sulfur(VI)fluoride exchange)and the lately discovered diazotransfer pro-cess.By encountering more and more near-perfect reactions,click chemistry is evolving and expanding on the fringe of the chemistry and dfferent scien-tific disciplines,destination unknown.
