Accessing cyclic carbonate monomers on a large scale is critical for the development of any new carbonate-based materials platform. The synthesis of carbonate monomers can be a challenging and tedious endeavor requiring multiple synthetic steps and purifications. To address this, we report a drastically improved process for the synthesis of carbonate monomers via a two-step route that avoids the use
Techniques regarding the synthesis of cyclic carbonate monomers are provided. For example, one or more embodiments described herein can comprise a method, which can include cyclizing a functionalized diol monomer with N,N′-carbonyldiimidazole, wherein the cyclizing produces a cyclic carbonate monomer and an imidazole carbamate. The method can also include activating the imidazole carbamate with an acid, wherein the activating promotes cyclization of the imidazole carbamate into the cyclic carbonate monomer.
