ICS: A01N035-04; C07C045-46; C07C049-84; C07C079-22. APPLICATION: JP 83-208088 5 Nov 1983. DOCUMENT TYPE: Patent CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 5 Title compds. I (R = alkyl, alkoxy, halo, NO2; R1, R3 = H, alkyl, halo, NO2, CF3; R2 = H, alkyl, alkali metal), useful as herbicides, were prepd. by treating II (R4 = OH, Cl) with III. Thus, stirring II (R = 4-Cl, R4 = Cl, 2-CF3) and III (R1 = R2 = Me, R3 = H) in the presence of FeCl3 gave 85% I (R = 4-Cl, R1 = R2 = Me, R3 = H, 2-CF3), which killed weeds such as barnyard grass, turnip more effectively than IV. .
