Process for preparing substituted isoxazoline compounds and their precursors The present invention relates to a new method of preparing halogenated styrene compounds of Formula (VIII), which are precursors in the process of synthesis of substituted isoxazoline compounds of Formula (I), wherein R1 to R5, R8 and R9 are described as in the description. The present invention relates further to the synthesis of compounds of formula (I) starting from acetophenones. The desired styrenes of formula are prepared from the appropriate substituted acetophenone. Asides bromo anilines react with formoxime. Obtained oximes undergo a cycloaddition with the styrenes and give isoxazolines. Compounds of formula (I) can then be prepared in a palladium catalyzed carbonylative ami- nation reaction of the isoxazolines.
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 yield of veterinary medicine. The compounds are represented by formula (I): wherein the respective substituents are defined in the specification.
The present invention relates to novel aryl isoxazoline derivatives having excellent insecticidal activity as insecticides and represented by the formula:
and their use as insecticides and acarizides.

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.
The invention relates to novel arylpyrroline compounds of formula (I) which have excellent insecticidal activity and which can thus be used as insecticides.
