Novel substituted phenoxypropionates of the formula ##STR1## in which Ar represents the group ##STR2## for the group ##STR3## in which Y represents a halogen atom or a trifluoromethyl group and b is 1 or 2, R represents a hydrogen atom or a methyl group, X represents a hydrogen atom, a halogen atom, a nitro group, a lower alkyl group or a lower alkoxy group, a and m each independently is 1 or 2, and n is 0, 1 or 2, and their use as herbicides. Novel intermediates of the formulae ##STR4## in which formulae R, X, m, n and a have the meanings given above, Z.sup.1 is a halogen atom and m is a hydrogen atom or an alkali metal atom.
公式为##STR1##的新型取代的苯氧基丙酸酯,其中Ar代表##STR2##而不是##STR3##,其中Y代表卤素原子或三氟甲基基团,b为1或2,R代表氢原子或甲基基团,X代表氢原子、卤素原子、硝基、低碳基或低碳氧基,a和m各自独立地为1或2,n为0、1或2,并用作除草剂。公式为##STR4##的新型中间体,其中公式中的R、X、m、n和a具有上述含义,Z.sup.1是卤素原子,m是氢原子或碱金属原子。
