Insecticidal N-(substituted arylmethyl)-4-[bis(substituted phenyl or pyridyl)methyl]piperidines

Abstract

Compounds of the following structure, the corresponding N-oxides and agriculturally acceptable salts thereof, are disclosed as effective insecticides: wherein U is —(CH2)n—; Q is hydroxy; and R is: and wherein V, W, Y, and Z are each hydrogen; X is a five- or six-membered heterocycle; optionally substituted with bromine, chlorine, fluorine, 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 pentahalothio, haloalkylthio, haloalkylsulfinyl, or haloalkylsulfonyl; phenyl substituted with —OC(M)2O—, where M is bromine, chorine or fluorine, to provide a dihalobenzodioxolyl fused ring; or pyridyl substituted with —OC(M)2O— to provide a dihalodioxolenopyridyl fused ring; 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 of the phenyl ring or the 5-position of the 2-pyridyl ring; each alkyl portion of said optional substituent on X wherein the optional substituent is alkyl, haloalkyl, alkoxyl, haloalkoxyl, alkoxyalkyl, or haloalkoxyalkyl contains from 1 to 4 carbon atoms; each heterocycle contains from 1 to 4 nitrogen atoms, 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.
