(57) [Summary] [Object] To provide a method for efficiently producing a carboxylic acid ester from an alcohol and a carboxylic acid under mild conditions. [Structure] When a carboxylic acid ester is produced by reacting an alcohol with an equivalent amount or a small excess of a carboxylic acid, A carboxylic acid anhydride represented by the general formula (4) (R 3 CO) 2 O (4) (wherein R 3 represents an aryl group which may have a substituent), and the general formula (5) (R 4 ) n SiX (4-n) (5) (wherein, R 4 represents a lower alkyl group, X represents a halogen atom, and n represents an integer of 1 to 3), and A method for producing a carboxylic acid ester, which comprises allowing a catalytic amount of a cationic catalyst to coexist. |
