It has now been found that certain novel oximino and hydrazono derivatives of N-benzyl-4-benzhydryl- and 4-benhydrolpiperidines, 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.sup.1 is hydrogen, alkyl, haloalkyl, alkoxyalkyl, alkylcarbonyl and alkylaminocarbonyl; X is oxygen, or NR.sup.2, Q is fluoro and hydroxy; Z is halogen, haloalkyl, haloalkoxy, pentahalothio, haloalkylthio, haloalkylsulfinyl, haloalkylsulfonyl, and --OCF.sub.2 O-- attached to two adjacent carbon atoms of the phenyl ring; n is 0 or 1; and, when X is NR.sup.2, R.sup.2 is hydrogen, alkyl, alkylcarbonyl, alkoxycarbonyl, or R.sup.1 and R.sup.2 taken together may be --C.sub.m H.sub.2.spsb.m, or --C.sub.2 H.sub.4 OC.sub.2 H.sub.4 --, where m is 3-9. Preferred compounds include those where R is hydrogen; R.sup.1 is alkyl; Q is hydroxy; X is oxygen; and Z is trifluoromethyl or trifluoromethoxy.
已经发现,N-苄基-4-苄基二苯甲基-和4-苄基羟基哌啶的某些新颖的氧肟和肼肟衍生物,以及它们相应的N-氧化物和农业可接受的盐可用作杀虫剂。这些化合物由式I表示:其中R为氢、卤素、烷基、烷氧基、二烷基胺基;R.sup.1为氢、烷基、卤代烷基、烷氧基烷基、烷基羰基和烷基氨基羰基;X为氧或NR.sup.2,Q为氟和羟基;Z为卤素、卤代烷基、卤代烷氧基、五卤硫、卤代烷硫基、卤代烷基磺酰基、卤代烷基磺基和连接到苯环的两个相邻碳原子的--OCF.sub.2 O--;n为0或1;当X为NR.sup.2时,R.sup.2为氢、烷基、烷基羰基、烷氧基羰基,或R.sup.1和R.sup.2一起可以是--C.sub.m H.sub.2.spsb.m,或--C.sub.2 H.sub.4 OC.sub.2 H.sub.4--,其中m为3-9。优选的化合物包括R为氢;R.sup.1为烷基;Q为羟基;X为氧;Z为三氟甲基或三氟甲氧基。
