Condensed-ring aryl compounds of formula (I) and use of the same as a agrochemical for controlling noxious organisms wherein (X)mQ, A, R1, (Y)n and the grouping -W1-W2-W3-W4- are as defined herein.
A visible-light-induced decarboxylative trifluoromethylation of alpha,beta-unsaturatedcarboxylicacids, which uses the Togni reagent as the CF3 source is disclosed. The corresponding trifluoromethylated alkenes were obtained in moderate to high yields with excellent functional group tolerance at ambient temperature. Preliminary mechanistic analyses suggest a radical-type mechanism.
The invention is directed to arylpyrrolidines compounds which exhibit excellent insecticidal efficacy and which may be used as in the agrochemical field or in the vield of veterinary medicine. The compounds are represented by formula (I):wherein the respective substituents are defined in the specification.
The invention relates to novel arylpyrroline compounds of formula (I) which have excellent insecticidal activity and which can thus be used as an insecticide.
