文摘

The radical addition of mercaptans (RSH) onto poly[2-(3-butenyl)-2-oxazoline], which is availablethrough a living/controlled cationic isomerization polymerization, can proceed smoothly in the absence of sidereactions, exhibiting the characteristics of a click reaction. The "thio-click" reaction can be performed underfeasible ([RSH]/[C=C] ~ 1.2-1.5, no transition metal additives) and mild conditions (generation of radicalswith UV light at room temperature) and goes to completion within a day. Hydrophobic fluoropolymers can beprepared in the same way as water-soluble (co-)polymers or glycopolymers, starting from readily available materials.
