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##
