Process for producing carboxylic acid esters from carboxylic acid halides and alcohols

摘要

A process for preparing carboxylic esters from carboxylic acid halides or carboxylic anhydrides by reacting one of these starting materials with an alcohol under the catalytic action of "onium" or metal salts of carboxylic acids to obtain high yields of products in anhydrous form in a technically simple manner. The process is especially well suited for preparing 1,1,1-trifluoroethyl trifluoroacetate.
