Abstract: New fluorinated tertiary butylamines of the formula ##STR1## are prepared from halogenated pivalic acid halides by a reaction sequence which comprises preparing the fluorinated pivalic acid and decomposition of the azide to the corresponding isocyanate. The isocyanate can be converted to the fluorinated tertiary butylamine acid addition salt by acid hydrolysis or directly to the amine by treatment with base. In addition, the present amines can be prepared by reaction of a pivalic acid amide with hypochlorite. The new butylamines can be used in the preparation of benzoic acid amides having insecticidal action.
