Abstract
Abstract A compound of the formula I: wherein R 1 is a hydrogen atom, a lower alkyl group or a halo(lower)alkyl group, R 2 and R, are, the same or different, each a hydrogen atom, a halogen atom, a nitro group, a cyano group or an optionally substituted lower alkyl, lower alkenyl, lower alkynyl, cyclo(lower)alkyl, lower alkoxy, lower alkenyloxy, lower alkynyloxy, cyclo(lower)alkoxy, lower alkylthio, lower alkenylthio, lower alkynylthio, cyclo-(lower)alkylthio, di(lower)alkylamino, lower alkylsulfonyl or lower alkylsulfinyl group, or R 2 and R 3 are combined together to form an optionally substituted 5- or 6- membered, saturated or unsaturated ring optionally having not more than two oxygen or sulfur atoms in the ring, R 4 is a halogen atom or a lower alkyl group, R 5 is a hydrogen atom or a lower alkyl group, X is an oxygen atom, a sulfur atom, a methylene group, a sulfonyl group, a sulfinyl group or an imino group and n is an integer of 1 to 4, which is useful as an insecticide and/or an acaricide.
