Estimating the term…
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.
A method of forming a 3-substituted-6-trifluoromethyl pyridine, the method comprising reacting a 6-trichloromethyl halogenated pyridine with a fluorinating agent to form a 6-trifluoromethyl halogenated pyridine.
A method of forming a 3-substituted-6-trifluoromethyl pyridine, the method comprising:
A method of using a 6-trichloromethyl halogenated pyridine to form a 3-substituted-6-trifluoromethyl pyridine, the method comprising reacting the 6-trichloromethyl halogenated pyridine with at least one of antimony pentafluoride and hydrogen fluoride to form a 6-trifluoromethyl halogenated pyridine.
