  • Certain oximinyl allophanates and their use as herbicides
    Patent number: 4115093
    Abstract: Disclosed are novel compounds of the formula ##STR1## in which when R.sup.1 and R.sup.2 are taken separately, R.sup.1 is selected independently from the group consisting of hydrogen and C.sub.1 -C.sub.7 alkyl and R.sup.2 is selected independently from the group consisting of C.sub.1 -C.sub.7 alkyl, phenyl and 2-furanyl, and, when taken together with the carbon atom to which they are attached R.sup.1 and R.sup.2 form a C.sub.3 -C.sub.8 cycloalkyl group; R.sup.3 is selected from the group consisting of C.sub.1 -C.sub.7 alkyl, allyl, phenyl, 3-halophenyl and 3,4-dihalophenyl; and R.sup.4 is selected from the group consisting of C.sub.1 -C.sub.7 alkyl, allyl, cyclohexyl, phenyl, halophenyl, tolyl, anisolyl, nitrophenyl, 3,4-dihalophenyl, 1-naphthyl, p-toluene sulfonyl, trihalomethylphenyl and 2,6-dinitro-4-trihalomethylphenyl.
