Using the same methodology, a number of 3,6-dinitro-l,8-naphthyridines (87a-87g) were converted with the LMA/PP system into the methylamino products (94). Tire methylamino group usually enters at position 4, but in cases where a chloro or methoxy substituent is present at C-2, 2,4-bis(methylamino) derivatives were isolated (97MI3). 

Nitration of 5-niethoxyquinoxaline furnishes a dinitro derivative, presumably 5-methoxy-6,8-dinitrociuinoxaline, but no mononitro derivative could be isolated. ...

Plant. Trifluralin was absorbed by carrot roots in greenhouse soils pretreated with the herbicide (0.75 Ib/acre). The major metabolite formed was a,a,a-trifluoro-2,6-dinitro-7V-(/i-propyl-toluene)-p-toluidine (Golab et al., 1967). Two metabolites of trifluralin that were reported in goosegrass Eleucine indica) were 3-methoxy-2,6-dinitro-A7A-dipropyl-4-(trifluoromethyl)benz-enamine and A-(2,6-dinitro-4-(trifluoromethyl)phenyl)-jV-propylpropanamide (Duke et al., 1991).
