    摘要: 4-Fluoro-3-phenoxy-benzyl 3-alken-1-yl-2,2-dimethylcyclopropanecarboxylates have the general formula ##STR1## wherein R represents alkyl or alkenyl,R.sup.1 represents hydrogen or alkyl, with the proviso that R and R.sup.1 are different, andR.sup.2 represents hydrogen, cyano or alkyl, alkenyl or alkynyl having in each case up to 4 carbon atoms,are obtained if 3-alken-1-yl-2,2-dimethyl-cyclopropanecarboxylic acids of the general formula ##STR2## wherein R and R.sup.1 have the meaning given above, or reactive derivatives of these acids, are reacted with 4-fluoro-3-phenoxy-benzyl alcohols of the general formula ##STR3## wherein R.sup.2 has the meaning given above, or with reactive derivatives of these alcohols, if appropriate in the presence of an acid acceptor and/or catalyst, and if appropriate using a diluent. The compounds of the formula (I) have a high pesticidal activity, especially against insects or acarids.
