Abstract
3-substituted-6-trifluoromethyl pyridines are useful synthetic intermediates in the preparation of the N-substituted (6-haloalkylpyridin-3-yl)alkyl sulfoximines, which are useful in forming potent insecticides. Methods of forming such 3-substituted-6-trifluoromethyl pyridines are disclosed. Also disclosed are methods of using 6-trichloromethyl halogenated pyridines to form 3-substituted-6-trifluoromethyl pyridines are disclosed.
