A method is provided for forming (3-trifluoromethylphenyl)acetonitrile through the intermediate .alpha.,.alpha.,.alpha.-trifluoro-.alpha.'-chloro-m-xylene. This intermediate is formed by selective chlorination of .alpha.,.alpha.,.alpha.'-trichloro-m-xylene under conditions which maximize yield and minimize the formation of undesired, non-recyclable chlorinated by-products.
