ABSTRACT:
Bis-substituted succinamides having the formula ##STR1## in which X is chlorine or bromine; R.sub.1 and R.sub.3 are each hydrogen, alkyl, haloalkyl, alkenyl, alkynyl, or benzyl; R.sub.2 and R.sub.4 are each hydrogen, alkyl, alkenyl, haloalkenyl, alkoxyalkyl, alkynyl, cycloalkyl, cyclopropylmethyl, furfuryl, and tetrahydrofurfuryl; R.sub.1 and R.sub.2 taken together along with the nitrogen form a non-aromatic heterocyclic ring; R.sub.3 and R.sub.4 taken together along with the nitrogen form a non-aromatic heterocyclic ring; provided that when R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each alkyl, then one of R.sub.1 or R.sub.2 and one of R.sub.3 or R.sub.4 is other than methyl; further provided that only one of R.sub.1 or R.sub.2 is hydrogen and only one of R.sub.3 or R.sub.4 is hydrogen. Compounds of this invention are useful as herbicides and includes those compounds in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each methyl.
