<p>It has now been found that certain novel oximino and hydrazono derivatives of N-benzyl-4-benzhydryl- and 4-benzhydrolpiperidines, and their corresponding N-oxides and agriculturally acceptable salts are useful as insecticides. These compounds are represented by formula (I) where R is hydrogen, halogen, alkyl, alkoxy, dialkylamino; R1 is hydrogen, alkyl, haloalkyl, alkoxyalkyl, alkylcarbonyl and alkylaminocarbonyl; X is oxygen, or NR2, Q is fluoro and hydroxy; Z is halogen, haloalkyle, haloalkoxy, pentahalothio, haloalkylthio, haloalkylsulfinyl, haloalkylsulfonyl, and -OCF¿2?O- attached to two adjacent carbon atoms of the phenyl ring; n is 0 or 1; and, when X is NR?2, R2¿ is hydrogen, alkyl, alkylcarbonyl, alkoxycarbonyl, or R?1 and R2¿ taken together may be -C¿m?H2m, or -C2H4OC2H4-, where m is 3-9. Preferred compounds include those where R is hydrogen; R?1¿ is alkyl; Q is hydroxy; X is oxygen; and Z is trifluoromethyl or trifluoromethoxy.</p> |
