Abstract
4-Alkyl-1-[4-[(trimethylsilyl)ethynyl]phenyl]-2,6,7-trioxabicyclo[2.2.2]octanes are potent insecticides with 24-h housefly topical LD 50 s depending on the 4-substituent, i.e., 0.4-0.7 μg/g for n-propyl, n-butyl, and tert-butyl and 68 μg/g for cyclohexyl. The 4-n-propyl- and 4-n-butyl-1-[4-[(trimethylsilyl)ethynyl]phenyl] compounds have almost the same potency to houseflies as their 1-(4-ethynylphenyl) analogues, suggesting that the trimethylsilyl compounds may be proinsecticides.
