Fluorine-substituted spirocarboxylic acid benzyl esters of the formula ##STR1## in which R.sup.1 represents hydrogen, cyano or alkyl, alkenyl or alkynyl, with in each case up to 4 carbon atoms,R.sup.2 represents a phenyl radical which is substituted by halogen and/or by optionally halogen-substituted phenoxy, with the proviso that the radical R.sup.2 contains in total at least one fluorine substituent, andR.sup.3, R.sup.4, R.sup.5 and R.sup.6 each represent hydrogen, halogen or alkyl, orR.sup.3 and R.sup.4, taken together, and/or R.sup.5 and R.sup.6, taken together, represent alkanediyl (alkylene) or a fused-on benzo radical,and the C atoms of the 5-member spirocyclic ring are linked to one another either by double bonds or by single bonds, which possess arthropodicidal properties.
摘要:
Substituted styrylcyclopropanecarboxylic acid esters of the formula ##STR1## in which R represents C.sub.1-4 -alkyl or an alcohol radical customary in pyrethroids,R.sup.1 represents alkoxy or alkylthio, either of which is optionally substituted by halogen andR.sup.2 represents hydrogen or alkoxy, orR.sup.1 and R.sup.2 together represent optionally halogen-substituted alkylenedioxy, andR.sup.3 represents hydrogen or chlorine,exhibit arthropodicidal activity. A novel synthesis is shown involving reaction of ##STR2## in the presence of an alkali metal cyanide to produce an end product wherein R is an .alpha.-cyano-3-phenoxybenzyl ester. ##STR3## is reacted with ##STR4## in the presence of a base to produce certain novel intermediates.

摘要:
3-Phenoxybenzyl alcohols and carboxylic acid esters thereof for combating pests of the formula ##STR1## in which R and R.sup.1 are different and each represent hydrogen, fluorine or bromine,R.sup.2 represents cyano or ethynyl andR.sup.3 represents the ##STR2## or the ##STR3## wherein the phenyl ring can optionally carry one or more substituents selected independently from halogen, alkyl, alkylthio and alkoxy with in each case 1 to 4 carbon atoms, nitro and methylenedioxy, andR.sup.4 and R.sup.5 are identical and each represent chlorine, bromine or methyl, andR.sup.2 represents hydrogen in case thatR.sup.3 represents the ##STR4## wherein R.sup.4 and R.sup.5 are identical and each represent chlorine or bromine andR.sup.3 represents the ##STR5## wherein the phenyl ring can carry the above mentioned substituents which possess insecticidal and acaricidal properties. The benzyl alcohols from which the esters are made are also new.
