Insecticidal compounds of the formula ##STR1## in which A and B are both halogen or hydrogen, or one of A and B is hydrogen, and the other of A and B is halogen; Z and W are independently O or S; the substituted benzofuranyl or benzothienyl group is attached at position 5 or 6; R is halogen; m is 0 to 3; R' is F or CF.sub.3 ; methods for their preparation and formulation, insecticidal compositions, and their use to control insects are disclosed.
Benzofurans of the formula ##STR1## wherein R.sup.1 is hydrogen, nitro, amino, phthalimido or acetamido, R.sup.2 is at least one of halo, cyano, alkyl(C.sub.1 -C.sub.8), cycloalkyl(C.sub.3 -C.sub.8), hydroxy, alkoxy(C.sub.1 -C.sub.8), acyl(C.sub.1 -C.sub.8), acyloxy(C.sub.1 -C.sub.8), alkoxy(C.sub.1 -C.sub.8)carbonyl, alkoxy(C.sub.1 -C.sub.8)carbonylalkyl(C.sub.1 -C.sub.8), phenyl, phenyloxy, trifluoromethyl or dialkyl(C.sub.1 -C.sub.8)amino, m is 0-3, and at least one of the carbon atoms of the benzene ring of said benzofuran is substituted. The compounds are intermediates in the preparation of pyrazoline insecticides.
N-[(Alpha-perhaloalkylbenzyloxy)pyridyl]-N'-benzoylurea compounds of the following structural formula are useful insecticides: ##STR1## in which R.sub.A is selected from the group consisting of -hydrogen, -halogen, -lower alkyl, -lower alkoxy, -benzyl, and -benzyloxy; R.sub.B is selected from -hydrogen and -halogen; R.sub.C and R.sub.D are both -hydrogen or together constitute a --COCO-- bridge; R is a perhaloalkyl substitutent; R.sub.3 is selected from the group consisting of -hydrogen, -halogen and -phenylthio; R.sub.4 is selected from the group consisting of -hydrogen, -halogen, -lower alkyl, -lower alkoxy, -lower alkoxyalkyl, -lower haloalkoxy, -lower alkylthio, -lower alkylsulfonyl, and -diallylamino; or R.sub.3 and R.sub.4 at adjacent ring positions constitute a --OCH.sub.2 O--, --CH.sub.2 C(CH.sub.3).sub.2 O--, or --CF.sub.2 CF.sub.2 O-- bridge; and R.sub.5 is --hydrogen or -lower alkyl.
