ABSTRACT:
Novel compounds of the general formula ##STR1## wherein R represents a hydrogen or halogen atom or a (cyclo) alkyl group, R.sup.3 represents H, CH.sub.3, or OCH.sub.3, n=0 or 1, and when n=0, R.sup.2 represents a hydrogen atom and R.sup.1 a hydrogen atom or a monovalent substituent thereby forming an alkoxide, ether, ester, or other alcohol derivative, and when n=1, each R.sup.1 and R.sup.2 independently represents one of the atoms specified for R.sup.1 when n=0, or R.sup.1 and R.sup.2 together represent a bivalent group thereby forming a cyclic ether, ester, or other diol derivative, have useful herbicidal properties.
