Title compds. (I; X1,X2,X3 = F, Cl, Br; R = substituted benzyl, 5-benzyl-3-furylmethyl; 2-methyl-3-alkyl-4-oxocyclopen-2-phenyl, 3-phenoxybenzyl, (S) or (R)α-cyano-3-ethynyl-α-phenoxybenzyl, 3,4,5,6-tetrahydro phthalimido methyl) were prepd. for use as pesticides. Thus, (1R-cis)2,2-dimethyl-3-(2',2'-dibromovinyl) cyclopropan-1-carboxylic acid reacted with Br in CCl4 to give (1R-cis)2,2-dimethyl-3-(1',2',2',2'-tetrabromoethyl)cyclopropan-1-carboxylate, which was converted into the acid chloride and treated with pyridine to give I (X1,X2,X3 = Br; R = 3,4,5,6-tetrahydronaphthalimido methyl).
