Polymer nitrile N-oxides directed toward catalyst- and solvent-free click grafting.

A general method for the one-pot synthesis of stable polymer nitrile N-oxides was developed by a combination of 1,1-diphenylnitroethene with a living anionic polymer. The polymer nitrile N-oxide served as a facile and effective grafting tool for use with polymers containing unsaturated bonds in a catalyst-free and solvent-free [2+3] cycloaddition.
