| Abstract: | Esters of 3-phenoxybenzyl alcohol and its α-cyano derivative with 2,2-dimethylcyclopropanecarboxylic acids bearing (E)- or (Z)-3-monohalovinyl side chains (haloiodo, bromo, chloro or fluoro) were synthesised and had moderate to high insecticidal activities, but these were generally lower than those of established pyrethroids with the corresponding 3-(dihalovinyl) side chains. Compounds with 3-(2-chloroprop-1-enyl) side chains were intermediate in potency between the related chrysanthemates and 3-(dichlorovinyl) esters. |
