ABSTRACT SUBSTITUTED DIPHEMYLETHER COMPOUNDS USEFUL AS HERBICIDES Novel compounds which exhibit herbicidal activity in combating weeds have the formula: Image wherein X is a nitro group or a chlorine atom and R is: (a) A group ZR3 where Z is oxygen or sulphur and R3 is a substituted aliphatic or alicyclic radical; (b) A group -NR1R2 where R1 is hydrogen or an optionally substituted aliphatic, alicyclic or phenyl radical and R2 is as R1 but may additionally represent hydroxy or optionally substituted alkoxy, or where R1 and R2 may together constitute a heterocyclic ring, -NR1R2; (c) A group -NS1S2 where S1 is preferably hydrogen and S2 contains an optionally substituted carboxylic ester group or a -CN or optionally substituted carboxy amide group; or (d) An optionally substituted phenoxy or phenylthio group or a sulpholanoxy group or an oxyimino group.
