The cyclic amidinium iodide effectively catalyzed the ring-expansion addition of epoxides with carbon dioxide under ordinary pressure and mild conditions to obtain the corresponding five-membered cyclic carbonates in high yield. The novel triazole-linked bifunctional five-membered cyclic carbonate was synthesized successfully by the click reaction of the azide- and the alkyne-substituted five-membered cyclic carbonates under ambient temperature in high yield. The chemical structure of the novel bis(cyclic carbonate) was characterized by one- and two-dimensional nuclear magnetic resonance spectra. The obtained bis(cyclic carbonate) was converted with commercially available diamines to poly(hydroxyurethane) containing triazole segment without catalyst in high yield. Analyses of the resulting poly(hydroxyurethane)s were performed by proton nuclear magnetic resonance, size exclusion chromatography, thermogravimetric analysis, and differential scanning calorimetry. © 2018 Wiley Periodicals, Inc.
