Abstract (en)
1. A 3-(2'-nitrophenoxy)-alpha-phenoxyalkanecarboxylic acid derivative of the general formula I see diagramm : EP0000474,P15,F3 wherein R1 represents hydrogen, C1 -C4 alkyl or C2 -C8 alkoxyalkyl, R2 represents hydrogen or C1 -C4 alkyl, R3 represents halogen, cyano or nitro, R4 represents halogen, cyano or trifluoromethyl, A represents cyano or the group -COB, B represents a radical OR5 , SR6 or NR7 R8 , R5 represents hydrogen or the cation of a base 1/n M**n (anion), wherein M represents an alkali metal or alkaline earth metal cation or an ammonium radical see diagramm : EP0000474,P15,F4 n as integer 1, 2 or 3 corresponds to the valency of the cation, whilst Ra , Rb , Rc and Rd , each independently of the other, represent hydrogen, benzyl or an alkyl radical which is unsubstituted or substituted by -OH, -NH2 or C1 -C4 alkoxy ; and R5 further represents, a C1 -C8 alkyl radical which can be unsubstituted or substituted by halogen, cyano, nitro, hydroxyl or a 5- to 6-membered nitrogen-containing heterocyclic ring system, and a C2 -C8 alkyl radical which can be interrupted by oxygen, sulphur, nitrogen, carbonyl or carbonyloxy, a C3 -C6 cycloalkyl radical, a C3 -C6 alkenyl or alkynyl radical which can be substituted by halogen, a phenyl or benzyl radical which can be substituted by halogen, cyano, nitro, C1 -C4 alkyl, C1 -C4 alkoxy or trifluoromethyl, R6 represents a C1 -C8 alkyl radical which can be substituted by halogen, cyano, nitro or hydroxyl or interrupted by oxygen, sulphur, nitrogen, carbonyl or carbonyloxy, a C3 -C6 cycloalkyl radical, a C3 -C6 alkenyl or alkynyl radical which can be substituted by halogen, a phenyl or benzyl radical which can be substituted by halogen, cyano, nitro, C1 -C4 alkyl, C1 -C4 alkoxy or trifluoromethyl, R7 represents hydrogen, a C1 -C8 alkyl radical which can be substituted by halogen, cyano or hydroxyl, and a C2 -C8 alkyl radical which can be interrupted by oxygen, R8 represents a C1 -C4 alkyl radical or a C3 -C4 alkyl radical, and R7 and R8 , together with the nitrogen atom to which they are attached, also represent a 5- to 6-membered heterocyclic radical which can be interrupted by oxygen, sulphur, an imino, C1 -C4 alkylimino or phenylimino group.
