1-Heterocyclic-2-pyrrolidinone analogs, and intermediates thereof, are described and are useful as aquatic and terrestrial herbicides and aquatic algicides. The compounds can also be used together with one or more herbicides to provide useful terrestrial herbicidal combinations. The compounds are prepared by cyclizing the intermediate amide with an acid acceptor.
