Abstract
Acyclic and alicyclic N-substituted halo-2-pyrrolidinones having the formula ##STR1## in which Q is oxygen or sulfur; R is lower alkyl, haloalkyl, alkenyl, cycloalkyl, cycloalkylalkyl, benzyl and chlorobenzyl; X is hydrogen or chlorine, Y is chlorine or bromine and Z is chlorine or bromine, provided that when R is allyl, Y and Z are each chlorine or bromine, and provided that when R is cyclohexyl, X is other than chlorine. The compounds of this invention are prepared by a novel process and are useful as herbicides.
