Process for the preparation of fluorinated carboxylic acid fluorides

摘要

Process for the preparation of fluorinated carboxylic acid fluorides Fluorinated carboxylic acid fluorides of the Formula I <IMAGE> (I) can be prepared from fluorinated vinyl ethers of the Formula II <IMAGE> (II) by heating the vinyl ethers to a temperature of 100 DEG to 350 DEG C. Perfluorinated carboxylic acids and derivatives thereof can be prepared from the carboxylic acid fluorides by secondary reactions, for example hydrolysis, esterification or aminolysis.
