Abstract: Substituted 2,3-dihydrobenzofurylmethyl esters of the formula I I where where R8 is hydrogen or alkyl of up to 5 carbon atoms, R9 is alkyl, haloalkenyl or haloalkynyl, each of up to 5 carbon atoms, R10 is halogen or alkyl of up to 5 carbon atoms, R11 is halogen or alkyl of up to 5 carbon atoms, A is halogen, alkyl, alkoxy, trihaloalkyl or trihaloalkoxy, each of up to 5 carbon atoms, cyano or nitro, B is alkyl, alkenyl or alkynyl, each of up to 4 carbon atoms, or an alicyclic radical of 3 to 7 carbon atoms and n is from 0 to 3, R2 is hydrogen, cyano or alkyl, alkenyl or alkynyl, each of up to 5 carbon atoms, and R3, R4, R5, R6 and R7 are identical or different and each is hydrogen, halogen or alkyl, alkenyl, alkynyl or alkoxy, each of up to 5 carbon atoms, and R9 may also be alkenyl of up to 5 carbon atoms if R2 is cyano or is alkyl, alkenyl or alkynyl, each of up to 5 carbon atoms. The novel compounds are useful in pest control.

Abstract: Racemic-cis-3-dihalovinyl- 2,2-dimethylcyclopropane carboxylic acid alpha-vinyl-3-phenoxybenzyl esters (I) are new (where R1 and R2 are halogen; and R3 is H, halogen or 1-3C alkyl). (I) are pref. prepd. from (I) and (II) by esterification. The esterification can be carried out e.g. by converting the acid to (II) into the halide and reaction of this with the alcohol (III); conversion of the alcohol (III) into a halide and reaction of this with the acid (II); condensn. of the acid (II) with the alcohol (III); or conversion of the acid (II) into an ester and trans-esterification of this with the alcohol (III). (I) are insecticides and acaricides with much higher activity than the corresp. trans isomers. They are suitable for use in plant protection, as well as in the hygiene, stored prods. and veterinary sectors. They are advantageously used in combination with pyrethroid synergists such as piperonyl butoxide.

Abstract: Novel carboxylic acid esters of the formula I where R1, R2 and R3 are identical or different and each is hydrogen, halogen or alkyl or alkenyl of up to 5 carbon atoms, Y is 3-(2,2-dihalogenovinyl)-2,2-dimethyl-cyclopropyl or a radical of the formula where R4 is unbranched or branched alkyl, alkenyl or alkynyl of up to 4 carbon atoms or is an alicyclic radical of 3 to 7 carbon atoms, R5 is halogen, alkyl or alkoxy of up to 5 carbon atoms, trihalomethyl, cyano or nitro and a is from 0 to 3 and Z is a radical of the formula +TR where X is oxygen, sulfur or -CH2-, R6, R7 and R8 are halogen or alkyl, alkoxy or haloalkyl of up to 5 carbon atoms and b, c and d are from 0 to 3, their preparation and their use in insect and arachnid control.

Abstract: Alpha-Vinyl-phenoxy-benzyl 3-dihalovinyl-2,2-dimethyl- cyclopropanecarboxylic acid esters (I) are new. R1, R2 and R3 are H, Cl, Br, F or 1-5C alkyl or alkenyl; X is O, S or CH2; R4 and R5 are halogen or 1-5C alkyl, alkoxy or haloalkyl; and a and b are 0, 1, 2 or 3; provided that R1, R2 and R3 are other than H or Br when a and b are both 0. (I) are insects and acaricides. Thus, when cabbage leaves are dipped in a 0.001% emulsion of alpha-vinyl-3-(p-fluorophenoxy) benzyl 3-(2,2-dichlorovinyl)-2,2-dimethylcyclo propanecarboxylate and placed on a moist filter in a Petri dish with 10 4th instar larvae of Plutella maculipennis, mortality is 80% after 48 hrs.
