| Abstract: | Several isobutenyl- and isobutyl-cyclopropanecarboxylates were synthesized. The insecticidal activities against the housefly of their 5-benzyl-3-furylmethyl or allethronyl esters were tested. Among the substituents on the cyclopropane ring, a methyl group cis to the ester linkage has been found to be essential for toxicity against the housefly and a trans-isobutenyl group greatly enhances the toxic activity. |
