    摘要: It has now been found that certain novel benzyloxyphenyl-substituted heterocycles are useful as pre-emergent and post-emergent herbicides. These compounds are represented by formula I: ##STR1## where Q is 1-substituted-6-trifluoromethyl-2,4(1H,3H)-pyrimidinedion-3 -yl, 4-difluoromethyl-4,5-dihydro-3-methyl-1,2,4-triazol-5(1H)-on-1-yl, 4-halo-5-difluoromethoxy-1-methylpyrazol-3-yl, a 3,4,5,6-tetrahydrophthalimid-1-yl, 8-thia-1,6-diazabicyclo�4.3.0!-nonane-7-on-9-iminoyl, 4-methyl-1,2,4-triazine-3,5-dion-2-yl, 3-chloro-4,5,6,7-tetrahydroindazol-2-yl, 1,4-dihydro-4-(3-fluoropropyl)-5H-tetrazole-5-on-1-yl or a 5,6,7,8-tetrahydro-1,2,4-triazolo-�4,3-a!pyridin-3(2H)-on-2-yl moiety; Z is oxygen, sulfur or CH.sub.2 ; n is 0 or 1, and W, X, Y, R, and R.sup.1 are as described in the specification. Preferred are those compounds where W is oxygen; X is hydrogen or fluoro; Y is methyl or ethyl; n is 1; Z is oxygen; R is methyl; and R.sup.1 is hydroxyalkyl or CH.sub.2 OCONHCH.sub.3.
