Document Type and Number:
WIPO Patent Application WO/2023/232002
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for preparing a carboxylate compound by means of the direct oxidation and esterification of alcohol under the catalysis of iron with oxygen or air as an oxidant. The method comprises: under the condition of 25-60ºC, directly oxidizing and esterifying an alcohol in an organic solvent by using iron nitrate (Fe(NO3)3·9H2O), an oxynitride and a Lewis acid as catalysts and oxygen or air as an oxidant, so as to generate a carboxylate compound. The present invention has various advantages including simple operation, the catalysts and raw materials being inexpensive and easily available, mild reaction conditions, a high yield, good compatibility between the functional groups of a substrate, it being possible to scale up the reaction, the reaction process being environmentally friendly and free of pollution, etc., and thus has industrial application prospects.
