Azomethine imine molecules possess a polar 1,3-dipole [N.sup.-]-[N.sup.+]=C fragment, which makes these compounds to be valuable precursors in the combinatorial chemistry of heterocycles prepared by cycloaddition
[E.sub.i] is the dominating energy when the cycloaddition
reaction proceeds from the RC to the IP.
Triazole polymers (mostly polyethers on the basis of commercial polyols) were also synthesized under neat conditions, by azide-alkyne cycloaddition
SGP at r.t.
