Effect of fluorine or oxygen atom(s) in propargylic position on the reactivity in click chemistry
摘要:
The use of especially designed omega-diynes allows to establish, through competitive reactions, the effect of C-F, C-OH, CF(2), C=0 and C(OMe)(2) substituents on the reactivity of neighbouring triple bonds in click chemistry and this gives not only a reactivity scale but also a direct access to the difference in activation energies between the competitive reaction pathways.
