METHOD FOR PRODUCING 3-TRIFLUOROMETHYLPHENYL-4-CYANOBENZYL KETONE

摘要

The invention relates to a method for producing 3-trifluoromethylphenyl-4- cyanobenzyl ketone by reacting a 3-trifluoromethyl benzoic acid-C1-C2-alkyl ester with 4-tolunitrile in an aprotic polar solvent or in an aprotic polar solvent mixture in the presence of at least one equimolar quantity of a base , whereby the base is selected among potassium alcoholates of primary C1-C4 alkanols.
