Combating arthropods with novel benzyl esters

摘要

Benzyl esters of the formula in which n is 1,2,3,4, or 5, R2 is hydrogen, C1-4-alkyl, cyano or ethynyl, R3 is radical of a carboxylic acid customary in pyrethroids or pyrethroid-like compounds, and at least one R1 is fluoroalkoxy or fluoroalkylmercapto, or two together are fluoromethylene- or fluoroethylene-dioxy, and the others, if present, are hydrogen or various radicals, which possess arthropodicidal properties. Various alcohols, amines, aldehydes, halides, and the like, corresponding to the alcohol moieties of the esters are also synthesized.
