INSECTICIDAL OXIMINO AND HYDRAZONO DERIVATIVES OF N-BENZYL-4-BENZHYDRYL- AND N-BENZYL-4BENZHYDROLPIPERIDINES

摘要

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; R<1> is hydrogen, alkyl, haloalkyl, alkoxyalkyl, alkylcarbonyl and alkylaminocarbonyl; X is oxygen, or NR<2>, Q is fluoro and hydroxy; Z is halogen, haloalkyle, haloalkoxy, pentahalothio, haloalkylthio, haloalkylsulfinyl, haloalkylsulfonyl, and -OCF2O- attached to two adjacent carbon atoms of the phenyl ring; n is 0 or 1; and, when X is NR<2>, R<2> is hydrogen, alkyl, alkylcarbonyl, alkoxycarbonyl, or R<1> and R<2> taken together may be -CmH2m, 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.
