Polymer Grafting via Catalyst-free Click Reaction of Kinetically Stabilized Nitrile N-Oxides

摘要

Click reaction can be used for the fabrication of sophisticated architectures including graft polymer, because of high reactivity and simple procedure. We have recently reported a usefulness of nitrile N-oxide as a click reaction1,2. Nitrile N-oxide reacts with various unsaturated bond-containing compounds to give corresponding heterocycles without any catalyst. In this study, we demonstrated the efficient polymer grafting via the catalyst-free click reaction of polymer nitrile N-oxide prepared by the facile chain-end modification and living ring opening polymerization (ROP).
