N-aryloxyacyl-n-phenyltetrahydrophthalamic acid derivative, process for producing the same, and herbicide containing the same as active ingredient

摘要

An N-aryloxyacyl-N-phenyltetrahydrophthalamic acid derivative represented by general formula (I), a process for producing the same, and a herbicide containing the same as the active ingredient, which is very useful as a herbicide because it can be widely applied to upland field, lowland, orchard, pasture, turf, forest and non-crop land, and is highly safe for crop. In formula (I), X and Y represent each independently hydrogen or halogen; R<1> represents hydrogen, halogen, lower alkyl, lower alkoxy, lower alkenyloxy, lower alkynyloxy, lower alkoxyalkoxy or lower alkoxycarbonylalkoxy; R<2> represents hydrogen or lower alkyl; R<3> represents hydroxy, lower alkoxy, lower alkenyloxy, lower alkynyloxy, lower alkoxy-alkoxy, benzyloxy or lower alkoxycarbonylalkoxy; and m represents an integer of 0 to 5.
