ABSTRACT:
A compound having the formula the formula ##STR1## where R is C.sub.1 -C.sub.12 alkyl, C.sub.5 -C.sub.6 cycloalkyl, C.sub.2 -C.sub.13 alkoxyalkyl, C.sub.7 -C.sub.9 aralkyl, phenyl, naphthyl, phenyl substituted with F, Cl, Br, I, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, methylenedioxy, NR.sup.3 R.sup.4 wherein R.sup.3 and R.sup.4 are the same or different and are hydrogen or C.sub.1 -C.sub.6 alkyl, C.sub.2 -C.sub.5 alkoxycarbonyl, phenoxy, NO.sub.2, cyano, trihalomethyl or trihalomethoxy where halo is F, Cl or Br or benzyl substituted with F, Cl, Br, I, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, methylenedioxy, C.sub.2 -C.sub.5 alkoxycarbonyl, carboxy, phenoxy, NO.sub.2, cyano, trihalomethyl or trihalomethoxy where halo is F, Cl or Br; R.sup.1 and R.sup.2 are the same or different and are C.sub.1 -C.sub.6 alkyl, C.sub.3 -C.sub.6 alkenyl, C.sub.5 -C.sub.6 cycloalkyl or R.sup.1 and R.sup.2 together are C.sub. 4 -C.sub.8 alkylene or C.sub.4 -C.sub.8 oxydialkylene is disclosed.
Furthermore, a process for forming this compound by reacting a compound having the formula ##STR2## wherein M is hydrogen or an alkali metal such as Li, Na or K and R has the meanings given above with a carbamoyl halide having the formula XCONR.sup.1 R.sup.2, wherein X is chlorine or bromine and R.sup.1 and R.sup.2 have the meanings above is taught.
In addition, a method of controlling weeds, both preemergence and postemergence, using a herbicidally effective amount of the compound of this invention is set forth.
Finally, a composition is disclosed, comprising the compound of this invention and a carrier therefor.
