This compound was prepared in the manner of Example II using 3.3 g of 2,2-dimethyl-3-(2-methyl-1-propenyl)cyclopropanecarbonyl chloride, whose preparation is described in J. Sci. Food and Agriculture, 18, 325 (1967), 4.3 g of α-trifluoromethyl-3-phenoxybenzyl alcohol, and 1.5 g of pyridine in 50 ml of toluene. Volatiles were distilled from the crude reaction product at 90°/0.08 mm for 1/2 hour, then at 100°/0.08 mm for 3/4 hour through a short path Kugelrohr distillation system to give as a residue 6.3 g of α-trifluoromethyl-3-phenoxybenzyl 3-(2,2-dimethylvinyl)-2,2-dimethylcyclopropanecarboxylate. The ir spectrum was consistent with the assigned structure.
