Abstract

Abstract 3-Phenoxybenzyl alcohols and carboxylic acid esters thereof for combating pests of the formula <IMAGE> (I) in which R and R1 are different and each represent hydrogen, fluorine or bromine, R2 represents cyano or ethynyl and R3 represents the <IMAGE> or the <IMAGE> 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, and R4 and R5 are identical and each represent chlorine, bromine or methyl, and R2 represents hydrogen in case that R3 represents the <IMAGE> wherein R4 and R5 are identical and each represent chlorine or bromine and R3 represents the <IMAGE> 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.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 56 words
A 3-phenoxybenzyl alcohol carboxylic acid ester of the formula ##STR78## in which R 2 represents hydrogen cyano or ethynyl and R 3 represents the ##STR79## 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.
Claim 2
Dependent Claim 56 words
A 3-phenoxybenzyl alcohol carboxylic acid ester of the formula ##STR78## in which R 2 represents hydrogen cyano or ethynyl and R 3 represents the ##STR79## 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.
Claim 3
Dependent Claim 48 words
An ester according to claim 1, in which R 3 represents the α-isopropylbenzyl radical, the ring of which can optionally carry one or more substituents selected independently from fluorine, chlorine, bromine, methylenedioxy, methoxy, ethoxy, methylthio, ethylthio, straight-chain or branched alkyl with 1 to 3 carbon atoms and nitro.
Claim 4
Dependent Claim 16 words

Dependent Claim 23 words
An arthropodicidal composition containing as active ingredient an arthropodicidally effective amount of a compound according to claim 1 in admixture with a diluent.
Claim 7
Dependent Claim 27 words
A method of combating arthropods which comprises applying to the arthropods, or to a habitat thereof, an arthropodicidally effective amount of a compound according to claim 1.
Claim 8
Dependent Claim 20 words
The method according to claim 7, wherein there is applied to a domesticated animal 3'-(4-fluorophenoxy)-α'-cyanobenzyl-α-isopropyl-4-chlorophenyl acetate or, ' -(3-fluorophenoxy)-α'-cyanobenzyl-α-isopropyl-4-chlorophenyl acetate.
