Abstract

Compounds corresponding to the formula

WHEREIN X represents chloro, bromo, or fluoro; R represents alkyl of one to 12 carbon atoms or a radical having the formula (CH2)nOR3 wherein n represents an integer of from 2 to 4 and R3 represents lower alkyl of one to four carbon atoms or phenyl; M represents hydrogen or methyl; R1 represents hydrogen, loweralkyl of one to four carbon atoms, amino or loweralkylamino of one to four carbon atoms; and R2 represents hydrogen, X, loweralkyl, amino or loweralkylamino, with the proviso that one of R1 or R2 is always amino or loweralkylamino and the other of R1 and R2 is always other than amino or loweralkylamino are prepared. These compounds are useful as herbicides and as active agents in compositions used as herbicides.
