New N-substd. 5-substd. methylene-aniline derivs. - useful as selective or total herbicides, and new 5-substd. nitrobenzene and aniline intermediates
Substd. aniline derivs. of formula (I) are new, where R1 and R2 = H, halo, 1-3C alkyl or alkoxy, CF3, phenoxy or benzyloxy (the last 2 opt. ring substd. ); R3 and R4 = H, 1-8C alkyl, alkenyl, alkynyl or halo; Y, which contains no more than 10 aliphatic C, is e.g. H, halo, CN, nitrate, 1-8C alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkylalkyl, cycloalkenylalkyl, OH, alkoxy, alkenyloxy, alkynyloxy, cycloalkoxy, cycloalkylalkoxy, cycloalkenyloxy, hydroxyalkyl, RO-alkyl, 1-8C alkylthio, alkenylthio, alkynylthio, cycloalkylthio, cycloalkenylthio, alkylthioalkyl, alkenylthioalkyl, alkynylthioalkyl, phenyl, phenoxy, phenylthio, ROCO, ROCO-alkoxy, RO.CO.O, R.CO, RCOO, RCO-alkoxy, RCO-alkyl, ROCO-alkyl, RCOO-alkyl, ROCO-alkyl, etc.; Y can also be NH2, NH2CO, NH2COO, NH2CS.O, NH2CO-alkoxy, NH2COO-alkyl, NH2CS.O-alkyl or NH2.CO-alkylthio: aminocarbonylalkylamino, alkyl-, alkoxy-, phenyl- or phenoxy-carbonylamino, phenyl- or phenoxy-carbonylalkylamino or alkoxycarbonyl alkylaminocarbonyl oximins; alkoxycarbonyloximino, alkoxycarbonyloximinocarbonyl or any 5 or 6-membered heterocycle contg. 1-3 O, N or S; Y can also be e.g. any of the gps. (i)-(viii), R = alkyl, cycloalkyl, alkenyl or alkynyl; m = 1 or 2; R5 = 1-6C alkyl, cycloalkyl, alkenyl, alkynyl or cycloalkenyl; R6 and R7 = H, 1-6C alkyl, cycloalkyl, alkenyl, alkynyl, cycloalkenyl or phenyl, R8 and R9 = R5 or H; n = 1-4; Q = alkali, alkaline earth or cation from inorganic or organic base; Z = (i) heterocyclic ring system attached via a ring N; or (ii) carbocyclic or heterocyclic ring system attached via N which is not part of a ring. Also new are intermediates (II) and (III).
