Method for preparing isocyanate by using amine and carbonyl fluoride

The invention discloses an efficient synthesis method for preparing corresponding isocyanate by enabling carbonyl fluoride to directly react with amine. The efficient synthesis method mainly comprises the following two steps: carrying out acylation reaction on the amine and the carbonyl fluoride according to a preferable proportion in an anhydrous inertial organic solvent under a sealed environment and a proper reaction condition, thus generating an intermediate-carbamyl fluoride; (2) carrying out dehydrofluorination on the intermediate-carbamyl fluoride under normal pressure and the proper reaction condition, thus obtaining the target isocyanate. During a reaction process, addition of a catalyst is not needed, the reaction conditions are mild, excessive carbonyl fluoride and a used solvent during the reaction process can be efficiently recycled and reused, and a by-product HF can be commercially sold after being collected and refined.

Syntheses of isocyanates via amines and carbonyl fluoride

Isocyanates are widely used in many different areas, but the most common synthesis route-phosgene route cannot fit the more and more rigorous restriction of safety and environment. Here, a facile synthesis method of isocyanates via amines and carbonyl fluoride is proven feasibly by expanding its applications to the syntheses of nine different isocyanates. And two differences with the phosgene route are proposed. The reaction could occur under milder conditions and afford isocyanates in good yields, especially for the isocyanates containing electron withdrawing groups. It is appealing for industrial application.
