Abstract
Abstract 1,3,3-trimethyl-6-azabicyclo-(3.2.1)-octane-6-carboxylic acid ester of the formula ##STR1## in which R is an aliphatic hydrocarbon residue which may also be substituted, a cycloaliphatic hydrocarbon residue which may also be substituted, an aromatic hydrocarbon residue which may also be substituted or an araliphatic hydrocarbon residue and wherein X and Y are oxygen or sulphur. The compounds of the invention are characterized by a superior herbicidal activity in particular against monocotyl weeds. They also have excellent selective properties for agricultural plants. The invention also embraces a process of making the compounds of the invention and compositions in which the compounds of the invention form at least one of the active components.
