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.
