First, cellulosic surfaces were functionalized with 4-pentynoic acid to introduce terminal alkyne moieties for the subsequent photo-induced coupling in heterogeneous phase. Next, the (primed) surfaces …
WebThiol-Yne Click Chemistry. In 1949, Bader et al. discovered that sulfhydryl (thiol) groups react with alkynes to form thiol-ether bonds. This reaction is known as the thiol-yne reaction or, more formally, alkyne hydrothiolation. Chemists mostly neglected this reaction until Fairbanks et al. popularized it in 2009.
