The phosgenation reaction, which is one of the most essential organic processes, is widely employed for fine chemical synthesis as well as resin production. Among the products obtained from the phosgenation reactions of hetero-nucleophiles, carbamoyl chloride is an essential building block that serves as a precursor for pharmaceutical and agrochemical compounds. The application of COCl2, a simple and traditional phosgenation reagent and reactive C1 compound, is avoided for the synthesis of these fine chemicals because of the restrictions placed on its application due to its high toxicity.
