Abstract
Abstract 2,2-Dimethyl-3-vinyl-cyclopropane carboxylic acid esters of halogenated benzyl alcohols of the formula <IMAGE> in which each R independently represents F, Cl, Br or CH3 and m and n each represent 0, 1, 2, 3, 4 or 5 subject to the sum of m+n being not more than 5, with the provisos that (i) when each R represents F or Br then m and n cannot both be 0, (ii) when each R represents Cl, then m represents 0, 1, 2, 3 or 4 and n represents 1, 2, 3, 4 or 5, and (iii) when each R represents CH3, then m represents 0 and n represents 5, which possess arthropodicidal properties.
