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.
提供了一种通过中间体α,α,α-三氟-α'-氯-间二甲苯形成(3-三氟甲基苯基)乙腈的方法。该中间体是通过选择性氯化α,α,α'-三氯-间二甲苯形成的,在最大化产量和最小化不需要再生的氯化副产物的形成的条件下。
