We have developed a novel synthetic method for azide-functionalized polymers using hypervalent iodine and NaN3. Azidyl radicals, formed by hypervalent iodine and NaN3, react to terminal alkenes at room temperature. We apply this reaction to radical polymerizations of monomers containing vinyl groups under two-phase conditions. In this system, azidyl radicals are generated at the emulsion droplet-water interface, so it is inhibited that free azidyl radicals are explosively generated and quenched on matrix. This system has an additional advantage that the polymers containing ‘clickable’ functionalities can be conveniently synthesized under mild conditions. The azide-functionalized polymers were characterized by various analytic methods such as infrared spectroscopy, nuclear magnetic resonance, and gel permeation chromatography. |
