ABSTRACT OF THE DISCLOSURE The invention relates to a process for the preparation of 3-amino-4-nitrophenyi phenyl ethers, certain novel 3-amino-4-nitro-phenyl phenyl ethers per se, herbicidal compositions containing 3-amino-4-nitro-phenyl phenyl ethers as active ingredient and methods for the use of 3-amino-4-phenyl phenyl ethers as herbicides. The 3-amino-4-nitro-phenyl phonyl ethers are prepared by reacting a nitrodiphenoxybenzene with an amine or salt thereof. This reaction enables the 3-amino-4-nitro-phenyl phenyl ethers to be obtained in good yield using readily available solvents such as water and starting materials which are readily preparable. The compounds prepared by the process of the present invention and the herbicidal compositions of the invention possess a marked herbicidal activity against weeds such as wild mustard, amaranth, goosefoot, camomile, prickly grass and slender foxtail. Methods for the use of the active compounds are described and examples of certain of the novel compounds are given. Herbicidal compositions containing the active compounds are described and exemplified. |
