摘要:
2,2-Dimethyl-3-(2-bromo-2-phenyl-vinyl)-cyclopropanecarboxylic acid 3-phenoxybenzyl ester of the formula ##STR1## which possess arthropodicidal properties. In addition, the new intermediate of the formula ##STR2## is produced by reacting an .alpha.-bromo-benzyl-phosphonic acid ester of the formula ##STR3## in which R.sup.6 each independently is alkyl or phenyl, or the two radicals R.sup.6 together are alkanediyl, with a 3-formyl-2,2-dimethyl-cyclopropanecarboxylic acid ester and saponifying. Also the compounds of the formula ##STR4## which are new when R.sup.1 is not alkyl, are produced by reacting triphenylphosphine and bromine to form dibromo-triphenylphosphorane, and reacting the dibromo-triphenylphosphorane without isolation with an .alpha.-hydroxy-benzyl-phosphonic acid ester of the formula ##STR5##

摘要:
Substituted 3-(1,2-dibromo-alkyl)-2,2-dimethyl-cyclopropane-1-carboxylic acid esters of the formula ##STR1## in which R.sup.1 is halogen or optionally substituted phenyl or optionally substituted alkyl,R.sup.2 is hydrogen, halogen or optionally substituted alkyl, andY is the radical of an alcohol customary in pyrethroids, with the proviso that Y is a benzyloxy radical which is substituted by halogen and optionally substituted by at least one additional radical if R.sup.1 is halogen or methyl,which possess pesticidal properties. The acid moieties of such esters wherein R.sup.1 is optionally substituted phenyl are new compounds.
