    摘要: Novel substituted phenoxypropionate of the formula ##STR1## in which R.sup.1 and R.sup.2 each independently are a hydrogen atom or a C.sub.1 to C.sub.6 alkyl group,X is a hydrogen or halogen atom or a nitro, C.sub.1 to C.sub.6 alkyl or C.sub.1 to C.sub.6 alkoxy group,a and n each independently are 1 or 2, andAr is a group of the formula ##STR2## wherein Y is a trifluoromethyl group, a halogen atom or a nitro, cyano or C.sub.1 to C.sub.6 alkyl group, andb is 1, 2 or 3,and their use as herbicides. Novel intermediates are taught, of the formula ##STR3## in which Z.sup.1 is halogen or a 4-hydroxyphenoxy group.
