Compounds corresponding to the formula ##STR1## wherein X represents chloro, bromo, or fluoro; R represents one of cyano (-CN), carbamoyl (--CONR.sup.3 R.sup.4) or carboxy (--COOH) or the carboxylic acid salts thereof; each of R.sup.3 and R.sup.4 independently represents hydrogen or alkyl of 1 to 8 carbon atoms; M represents hydrogen or loweralkyl; R.sup.1 represents hydrogen, loweralkyl, amino or loweralkylamino of 1 to 4 carbon atoms; and R.sup.2 represents hydrogen, X, loweralkyl, amino or loweralkylamino, with the proviso that one of R.sup.1 or R.sup.2 is always amino or loweralkylamino and the other of R.sup.1 and R.sup.2 is always other than amino or loweralkylamino are prepared. These compounds are useful as herbicides and as active agents in compositions used as herbicides.
该文献描述了一系列化合物的公式为##STR1##其中X代表氯,溴或氟;R代表氰基(-CN),氨基甲酰(-CONR.sup.3 R.sup.4)或羧基(-COOH)或其羧酸盐;每个R.sup.3和R.sup.4独立地代表1至8个碳原子的氢或烷基;M代表氢或低烷基;R.sup.1代表氢,低烷基,氨基或1至4个碳原子的低烷基氨基;R.sup.2代表氢,X,低烷基,氨基或低烷基氨基,但其中R.sup.1或R.sup.2始终是氨基或低烷基氨基,而R.sup.1和R.sup.2中的另一个始终不是氨基或低烷基氨基。这些化合物可用作除草剂,并作为除草剂组合物中的活性剂。
