Polyurethanes exhibit excellent coating properties for many applications. Facing the continuous growth of the polyurethane coating market, in the last few years many scientists have addressed the safety and sustainability of their production. This paper highlights the efforts that have been pursued in this direction from both the academic and industrial perspectives and covers aspects ranging from the substitution of petroleum‐based monomers by biobased equivalents to the development of novel synthetic pathways for the production of polyhydroxyurethanes. © 2018 Society of Chemical Industry

“…However, this method is no longer used because of the toxicity of phosgene . Moreover, the cycloaddition of CO 2 with epoxides with 100% atom economy has been demonstrated to be a promising method from the point of view of green chemistry . Despite the efficiency of this route, several limitations have been exposed such as the volatility and toxicity of epoxides.…”

In recent years increasing attention has been given to the efficacious synthesis of organic carbonates from sustainable CO2. The carboxylation/hydration reaction of alcohols with CO2 stands out for its environmentally friendly and economic features. However, it faces several substantial challenges such as thermodynamic limitations, low catalytic efficiency, and product selectivity. In this article, recent advances in the development of catalytic methods for the synthesis of organic carbonates through carboxylation/hydration reaction of alcohols with CO2 are summarized. Catalytic schemes (metal and metal‐free catalysis), water‐dehydration strategies, and catalytic mechanisms are also discussed in detail. The review covers the carbonylation cyclization of various alcohols and the equivalent of CO2, i.e. urea. Finally, an overview is provided of the recent breakthrough in the development of thermodynamically favorable processes involving alcohols and CO2. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.

[33] However, some of the catalysts and protocols have drawbacks such as the use of a high temperature and CO 2 pressure, metallic ions, high-cost procedures for product separation and/or catalyst synthesis, low activity, poor stability, unsatisfactory reusability, and need a long reaction time.…”

Green and sustainable synthesis is considered as a safer alternative to the conventional synthetic processes owing to its environmental friendly nature, atom economy, cost‐effectiveness, and easy handling. Herein, the catalytic efficiency of poly(4‐vinylpyridine) supported iodine (P4VP/I2) as a metal‐free and organocatalyst system was studied and approved for an efficient chemical fixation of CO2 into cyclic carbonates which is performed via the coupling of CO2 with epoxides. The high conversion and excellent selectivity were obtained for a broad range of epoxides in the presence of catalytic amount of P4VP/I2 under solvent‐free conditions. The heterogeneous catalyst could be recovered and regenerated over several times with no significant loss of catalytic activity. The possible mechanism was described for the catalytic performance of P4VP/I2 based on the synergetic effect of the Lewis acid and base sites and nucleophilic anion.
