摘要:
Novel urea derivatives of the formula ##STR1## wherein R and R.sub.1 are individually selected from the group consisting of hydrogen, chlorine, bromine, nitro, trifluoromethyl, lower alkyl of 1 to 6 carbon atoms and lower alkoxy of 1 to 6 carbon atoms, n is 0 or 1, X is selected from the group consisting of lower alkyl of 1 to 6 carbon atoms optionally substituted with halogen and a nitrogen heterocyclic optionally containing 1 or more other heteroatoms, Y is selected from the group consisting of hydrogen, alkyl of 1 to 4 carbon atoms and S--Z wherein Z is a nitrogen heterocyclic optionally containing 1 or more other heteroatoms and the dotted lines indicate that the compound of formula I may contain no oxygen bound to the sulfur atom or may be in sulfoxide or sulfonyl form which are useful as herbicides and thereon preparation.
