    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.

    摘要： Methyl-substituted tetrahydro-2-pyrimidinone derivatives of the general formula ##STR1## in which each Ar, independently of each other, represents an aryl group which is optionally mono- or poly-substituted by substituent(s) selected from halogen, C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 alkoxy, C.sub.1 to C.sub.6 alkylthio, nitro, phenoxy and trifluoromethyl, andR.sup.1, R.sup.2 and R.sup.3 independently represent a hydrogen atom or a methyl group,provided that at least one of R.sup.1, R.sup.2 and R.sup.3 represents a methyl group,are new and find use as herbicides, in particular as selective herbicides which may be used on weeds in crops such as cotton and rice. The N,N'-diaryl-N-haloalkyl-ureas which are starting materials for the production of compounds of formula (I) are also new.
