Combating arthropods with novel fluorine-containing phenylacetic acid esters

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.sup.1 represents C.sub.2-4 -alkyl, C.sub.2-4 -alkenyl or cyclopropyl, X represents H, halogen, alkyl, alkoxy, OCHF.sub.2, SCHF.sub.2, SCClF.sub.2 or SCF.sub.3 and X.sup.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.

Dependencies are inferred from the claim text.
