Abstract
Compounds of the formula ##STR1## in which Ar is substituted or unsubstituted phenyl, naphthyl, or thienyl; Z is oxygen, sulfur, or methylene; and Ar' is 2-methyl[1,1'-biphenyl]-3-yl, 3-phenoxyphenyl, 4-fluoro-3-phenoxyphenyl, or 6-phenoxy-2-pyridyl exhibit pyrethroid-like insecticidal and acaricidal activity and are relatively harmless to aquatic fauna.

A compound of the formula ##STR13## in which Ar is a phenyl or thieynl group which may be substituted by (C.sub.1-6)alkyl, halo, (C.sub.1-4)haloalkyl, (C.sub.1-4)alkoxy, (C.sub.1-4)haloalkoxy, or by a substituent having the structure --A--(CR.sup.1 R.sup.2)--A-- where R.sup.1 and R.sup.2 are independently hydrogen, halogen, or (C.sub.1-2)alkyl, n is 1 or 2, and each A is O or CH.sub.2 and is bonded to an adjacent carbon atom of the aromatic ring;
- Z is oxygen, sulfur, or methylene;
- and Ar' is phenoxylphenyl, 2-methyl[1,1'-biphenyl]-3-yl, or 6-phenoxy-2-pyridyl each optionally substituted with halo or lower alkyl.
A compound of the formula ##STR14## in which Ar is a pheny or thienyl group which may be substituted by (C.sub.1-6)alkyl, halo, (C.sub.1-4)haloalkyl, (C.sub.1-4)alkoxy, (C.sub.1-4)haloalkoxy, or by a substituent having the structure --A--(CR.sup.1 R.sup.2)--A-- where R.sup.1 and R.sup.2 are independently hydrogen, halogen, or (C.sub.1-2)alkyl, n is 1 or 2, and each A is O or CH.sub.2 and is bonded to an adjacent carbon atom of the aromatic ring;
- and Ar' is a phenoxyphenyl, 2-methyl[1,1,'-biphenyl]-3-yl, or 6-phenoxy-2-pyridyl each optionally substituted with halo or lower alkyl.
A compound of the formula ##STR15## in which Ar is a phenyl or thienyl group which may be substituted by (C.sub.1-6)alkyl, halo, (C.sub.1-4)haloalkyl, (C.sub.1-4)alkoxy, (C.sub.1-4)haloalkoxy, or by a substituent having the structure --A--(CR.sup.1 R.sup.2)--A-- where R.sup.1 and R.sup.2 are independently hydrogen, halogen, or (C.sub.1-2)alkyl, n is 1 or 2, and each A is O or CH.sub.2 and is bonded to an adjacent carbon atom of the aromatic ring;
- and Ar' is phenoxyphenyl, 2-methyl[1,1'-biphenyl]-3-yl, or 6-phenoxy-2-pyridyl each optionally substituted with halo or lower alkyl.
