Various 2'-phenoxymethanesulfonanilide derivatives were synthesized and evaluated for antiinflammatory and analgesic activities. Some compounds bearing an electron-attracting substituent at the 4'-position strongly inhibited adjuvant-induced arthritis in rats and acetic acid-induced writhing syndrome in mice without causing gastro-intestinal irritation. Among them, 4'-cyano-(FK867) and 4'-acetyl-(FK3311)
Phenoxybenzonitriles, halo-substituted on the phenoxy ring and halo- or alkyl-substituted on the benzonitrile ring ortho to the para-cyano position, form a new class of herbicides. These substituted phenoxybenzonitriles and herbicidal compositions containing them are highly effective as pre-emergence and post-emergence herbicides, especially at low use concentrations. They are highly effective against Crabgrass, Yellow Foxtail grass and Barnyard grass, annual grass weeds which reproduce by seed. They are also highly effective against Johnson grass, a perennial grass weed which reproduces by seed and underground rhizomes, and Pigweed, an annular broadleaf weed which reproduces by seed.
