Compounds of the following structure, the corresponding N-oxides and agriculturally acceptable salts, are disclosed as effective insecticides:
in which
U is —(CH2)n—;
Q is hydroxy;
R is
in which
V, W, Y, and Z are each hydrogen;
X is a five- or six-membered heterocycle; optionally substituted with halogen, cyano, alkyl, haloalkyl, alkoxy, haloalkoxy, alkoxyalkyl, haloalkoxyalkyl, or aminocarbonyl; and the heterocycle is optionally connected to the phenyl ring through a —O—, —S—, —(CH2)p, —C(O)—, or —O—(CR3R4)q linkage;
R1 and R2 are independently selected from phenyl or pyridyl substituted with haloalkyl or haloalkoxy;
R3 and R4 are independently selected from hydrogen and methyl;
n and p are independently 1, 2, or 3; and q is 1 or 2;
with the proviso that at least one of R1 and R2 is substituted in the para position; no more than two of R3 and R4 are methyl; each aliphatic moiety contains not more than 4 carbon atoms; halogen means bromine, chlorine, or fluorine; each heterocycle contains from 1 to 4 nitrogen atoms, or 1 or 2 oxygen or sulfur atoms, or 1 or 2 nitrogen atoms and an oxygen or sulfur atom;
and the corresponding N-oxides and agriculturally acceptable salts.
