Novel compounds of the general formula
wherein R represents a hydrogen or halogen atom or a (cyclo) alkyl group, R3 represents H, CH3, or OCH3, n=0 or 1, and when n=0, R2 represents a hydrogen atom and R1 a hydrogen atom or a monovalent substituent thereby forming an alkoxide, ether, ester, or other alcohol derivative, and when n=1, each of R1 and R2 independently represents one of the atoms specified for R1 when n=0, or R1 and R2 together represent a bivalent group thereby forming a cyclic ether, ester, or other diol derivative, have useful herbicidal properties.
通式中 R 代表氢原子、卤素原子或(环)烷基,R3 代表 H、CH3 或 OCH3,n=0 或 1,当 n=0 时,R2 代表氢原子,R1 代表氢原子或一价取代基,从而形成烷氧基、醚、酯或其他醇衍生物,当 n=1 时,R1 和 R2 各自独立地代表 n=0 时 R1 所指定的原子之一,或 R1 和 R2 共同代表二价基团,从而形成环醚、酯或其他二元醇衍生物的新型化合物具有有用的除草特性。
