Abstract
Abstract Fluorine-containing phenylacetic acid esters of the formula ##STR1## in which R represents the radical of an alcohol customary in the case of pyrethroids, R 1 represents C 2-4 -alkyl, C 2-4 -alkenyl or cyclopropyl, X represents H, halogen, alkyl, alkoxy, OCHF 2 , SCHF 2 , SCClF 2 or SCF 3 and X 1 can vary widely or form a fused ring with X, the overall compound necessarily containing a fluorine atom, which compounds possess arthropodicidal properties. Intermediates therefor and an overall synthesis from an alcohol of the formula ROH and a toluene of the formula ##STR2## are also shown.
