Abstract
Abstract Fluorine substituted phenoxybenzylcarbonyl derivatives of the formula ##STR1## in which R 1 represents hydrogen, cyano or ethynyl and R 2 represents the radical ##STR2## wherein R 3 and R 4 , which are identical, each represent chlorine, bromine or methyl, or R 2 represents the radical ##STR3## wherein R 5 represents a phenyl ring which optionally carries one or more substituents each selected independently from halogen, alkyl, alkylthio and alkoxy each with 1-4 carbon atoms, nitro and methylenedioxy, which possess arthropodicidal properties. The benzyl alcohol components of these esters are also new.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
78 words
A fluorine-substituted phenoxybenzylcarbonyl derivative of the formula ##STR32## in which R 1 represents hydrogen, cyano or ethynyl and R 2 represents the radical ##STR33## wherein R 3 and R 4 , which are identical, each represent chlorine, bromine or methyl, or R 2 represents the radical ##STR34## wherein R 5 represents a phenyl ring which optionally carries one or more substituents each selected independently from halogen, alkyl, alkylthio and alkoxy each with 1-4 carbon atoms, nitro and methylenedioxy.
Claim 2
Dependent Claim
78 words
A fluorine-substituted phenoxybenzylcarbonyl derivative of the formula ##STR32## in which R 1 represents hydrogen, cyano or ethynyl and R 2 represents the radical ##STR33## wherein R 3 and R 4 , which are identical, each represent chlorine, bromine or methyl, or R 2 represents the radical ##STR34## wherein R 5 represents a phenyl ring which optionally carries one or more substituents each selected independently from halogen, alkyl, alkylthio and alkoxy each with 1-4 carbon atoms, nitro and methylenedioxy.
Claim 3
Dependent Claim
55 words
A compound according to claim 1, in which R 1 represents hydrogen or cyano and R 2 represents the 2,2-dimethyl-3-(2,2-dichloro- 2,2-dibromo- or 2,2-dimethyl-vinyl)-cyclopropane radical or the α-isopropylbenzyl) radical which optionally carries one or more substituents in the ring selected independently from fluorine, chlorine, bromine and straight-chain or branched alkyl with 1 to 3 carbon atoms.
Claim 4
Dependent Claim

Claim 8
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 9
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 10
Dependent Claim
35 words
The method according to claim 8, in which said compound is 3-(3-fluorophenoxy)-4-fluoro-α-cyanobenzyl 1 -isopropyl-4'-chlorophenyl-acetate, 3-(3-fluorophenoxy)-6-fluorobenzyl 2,2-dimethyl-3-(2,2-dichlorovinyl)-cyclopropanecarboxylate or 3-(4-fluorophenoxy)-4-fluoro-α-cyanobenzyl 2,2-dimethyl-3-(2,2-dichlorovinyl)-cyclopropanecarboxylate, and is applied to domesticated animals thereby to free such animals from ectoparasitical insects and acarids.
