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.
通式为##STR1##的新化合物,其中R代表氢或卤素原子或(cyclo)烷基团,R.sup.3代表H、CH.sub.3或OCH.sub.3,n=0或1,当n=0时,R.sup.2代表氢原子,R.sup.1代表氢原子或单价取代基,从而形成醇盐、醚、酯或其他醇衍生物,当n=1时,每个R.sup.1和R.sup.2独立地代表R.sup.1在n=0时指定的原子之一,或者R.sup.1和R.sup.2一起代表一个双价基团,从而形成环状醚、酯或其他二元醇衍生物,具有有用的除草性能。
