An N-substituted benzamide of the formula ##STR1## in which R.sup.1 represents hydrogen or alkyl, R.sup.2 represents halogenoalkyl with more than one carbon atom, or represents cycloalkyl which is substituted by halogen or halogenoalkyl and R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 are identical or different and represent hydrogen, halogen, nitro, alkyl, halogenoalkyl, halogenoalkoxy or halogenoalkylthio, or represent the radical--CONR.sup.1 R.sup.2. The N-substituted benzamides are active as insecticides and nematicides and can be prepared by reacting a benzoyl halide of the formula (II) ##STR2## in which R.sup.8, R.sup.9, R.sup.10, R.sup.11 and R.sup.12 are identical or different and represent hydrogen, halogen, nitro, alkyl, halogenoalkyl, halogenoalkoxy or halogenoalkylthio, or represent the radical --CO--Hal and Hal represents halogen, with an amine of the formula (III) HNR.sup.1 R.sup.2 (III) in which R.sup.1 and R.sup.2 have the abovementioned meanings, or with corresponding hydrohalides.
公式为##STR1##的N-取代苯甲酰胺,其中R.sup.1代表氢或烷基,R.sup.2代表含有多个碳原子的卤代烷基,或代表被卤素或卤代烷基取代的环烷基,而R.sup.3,R.sup.4,R.sup.5,R.sup.6和R.sup.7相同或不同,代表氢、卤素、硝基、烷基、卤代烷基、卤代烷氧基或卤代烷硫基,或代表基团--CONR.sup.1R.sup.2。这些N-取代苯甲酰胺具有杀虫和杀线虫活性,可以通过将公式(II)的苯甲酰卤与公式(III)的胺反应制备得到,其中R.sup.8,R.sup.9,R.sup.10,R.sup.11和R.sup.12相同或不同,代表氢、卤素、硝基、烷基、卤代烷基、卤代烷氧基或卤代烷硫基,或代表基团--CO--Hal,而Hal代表卤素,或与相应的氢卤酸盐反应。
