Synthetic studies of fluorine-containing compounds for household insecticides

The discovery stories of three fluorine-containing insecticides in our laboratory are described, i.e. amidoflumet, a new trifluoromethanesulfonanilide with high miticidal activity against various house dust mites, Metofluthrin, a potent new fluorinated pyrethroid with extremely high knockdown activity against various mosquitoes, and a new α-pyrone compound, 3-[1R-trans-(2-trifluoromethyl)cyclopropanecarbonyl]-4-hydroxy-6-methyl-2-pyrone with outstanding insecticidal activity against Blattella germanica.
