| 摘要 |
<p>The invention relates to novel oxalyl dianilides of the formula <IMAGE> (I) wherein R is hydrogen, halogen, C1-C4alkyl, methoxy, ethoxy, C1-C2 fluoroalkoxy containing 1 to 5 fluorine atoms, R1 is hydrogen, halogen, methyl, methoxy, ethoxy, C1-C2 fluoroalkoxy containing 1 to 5 fluorine atoms, C1-C3alkylthio or cyano, R2 is hydrogen, halogen, methyl or methoxy, R3 and R4 are each independently hydrogen or methyl, R5 is hydrogen, halogen, methyl, acetyl or trifluoromethyl, R6 is hydrogen, halogen, methyl, trifluoromethyl or carbalkoxy containing 1 to 4 carbon atoms in alkyl moiety, and R7 is hydrogen, C1-C3fluoroalkyl containing 1 to 7 fluorine atoms, C1-C3alkoxy, C1-C3haloalkoxy containing 1 to 7 halogen atoms or is the <IMAGE> radical, in which R8 is hydrogen, chlorine, trifluoromethyl or a perhalogenated ethyl radical and X is hydrogen or chlorine; or is the <IMAGE> radical, in which R9 is hydrogen, chlorine, bromine, methoxy or ethoxy; or is the <IMAGE> radical, in which R10 and R11 are each independently hydrogen,halogen, methyl, trifluoromethoxy or trifluoromethyl and Y is an oxygen or a sulfur atom; or is the <IMAGE> radical, in which R12 and R13 are C1-C5alkyl, with the proviso that R5, R6 and R7 may not simultaneouly be hydrogen. The invention also relates to the preparation of these compounds and to compositions containing them for controlling insects and representatives of the order Acarina. The novel compounds have larvicidal activity, in particular against plant destructive insects.</p> |
