Abstract

Novel 2-(2,2-dihalogenovinyl)-3,3-dimethylcyclopropanecarboxylic acid derivatives of the formula ##STR1## e.g. amides, thioamides, oxazolines, amidoximes and hydroxamic acids, are produced by reacting the new compounds ##STR2## with a base in the presence of a diluent. New compounds of the formula ##STR3## are produced by reacting ##STR4## with ##STR5##
