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, haloalkyl, haloalkoxy, pentahalothio, haloalkylthio, haloalkylsulfinyl, haloalkylsulfonyl, and --OCF2 O-- attached to two adjacent carbon atoms of the phenyl ring; n is 0 or 1; and, when X is NR2, R2 is hydrogen, alkyl, alkylcarbonyl, alkoxycarbonyl, or R1 and R2 taken together may be --Cm H2.spsb.m, or --C2 H4 OC2 H4 --, where m is 3-9. Preferred compounds include those where R is hydrogen; R1 is alkyl; Q is hydroxy; X is oxygen; and Z is trifluoromethyl or trifluoromethoxy.Field of SearchNitrogen attached indirectly to the piperidine ring by nonionic bondingPlural acyclic nitrogens bonded directly to the same carbon or single bonded directly to each other Chalcogen attached indirectly to the piperidine ring by nonionic bonding The chalcogen, X, is in a -C(=X)- group Nitrogen attached indirectly to the piperidine ring by nonionic bonding |
