As one of the CCU technologies, non-reductive synthetic methods of useful chemicals for production useful chemicals using CO₂ as carbonyl source have attracted significant attentions. We have developed synthetic method for isocyanates, which are industrially important raw materials of polyurethane production, from CO₂. In our method, carbamates were first synthesized from CO₂ and amines, and subsequently, the carbamates were converted into isocyanate through a dealcoholization reaction.
