Web5 Oct 2024 · Note that this click reaction doesn’t use a copper (I) catalyst; instead, it’s driven by strain. Specifically, the alkyne they used was a difluorooctyne – an eight-sided ring alkyne that is not stable because the two fluorine atoms – greedy for electrons – are straining the ring. ... short for ‘strain-promoted azide-alkyne ... Web2 Jun 2011 · Morvan and coworkers previously reported that copper-catalyzed azide-alkyne click chemistry of ODNs on solid support required the use of microwaves to drive the reaction to completion; 26 we find that strain-promoted, copper-free click reactions on solid support go to completion without the need for microwave irradiation.
