Norbornene derivatives from a metal-free, strain-promoted cycloaddition reaction: New building blocks for ring-opening metathesis polymerization reactions

Abstract

The preparation of new ring opening metathesis polymerization (ROMP) monomers using a 1,3-dipolar cycloaddition between aryl azides and norbornadiene is described. Various norbornenetriazolines, obtained through a solvent-and catalyst-free reaction, can subsequently be incorporated into polymer backbones through ROMP reactions. Furthermore, thermal decomposition of the triazoline moiety can allow for further polymer functionalization. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2015, 53, 2357–2362
