Method for the racemization of (2)-2-(4-difluoromethoxyphenyl)-3-methylbutyric acid
A method for the racemization and hydrolysis of alkyl esters of (-)-2-(4-difluoromethoxyphenyl)-3-methylbutyric acid, followed by the resolution of said resulting racemic acid into its optically active components via salts prepared from the same with optically active amines and recovery of the dextrorotatory (+) isomer therefrom. The present invention also relates to insecticidal pyrethroids prepared from (+)-2-(4-difluoromethoxyphenyl)-3-methylbutyric acid.

Method for the alkylation of phenylacetonitriles
A method for the alkylation of certain substituted phenylacetonitriles with alkylhalides in the presence of solid particulated alkali metal hydroxides under essentially anhydrous conditions. Trialkylamine catalysts may optionally be utilized. Compounds obtained by this method, some of which are valuable intermediates in the preparation of pyrethroid pesticides, are described.
