Abstract: Production of aldimino- and ketimino- -nitroaryl ethers of the formula
IN WHICH R1 is (m+n) -valent aryl, R2 and R3 each individually is selected from the group consisting of hydrogen, alkyl of up to eight carbon atoms, cycloalkyl, aralkyl, aryl and heterocyclic, with the proviso that R2 and R3 when taken together with the adjacent carbon atom to which they are attached form a ring selected from the group consisting of a 5- to 7-membered isocyclic and heterocyclic ring, m and n each individually is a number from one to two, R4 is (z+l) -valent aryl, and z is an number from one to two, by reacting the corresponding Schiff''s base of the formula
IN WHICH R1, R2, R3, m and n are the same as defined above with an aromatic halo-nitro compound of the formula X -R4 (-NO2)z IN WHICH X is fluoro, chloro or bromo, and R4 and z are the same as defined above, e.g. at about -20* to +200* C., in the presence of an acid acceptor; said ethers being intermediates for producing plant protection agents, e.g. fungicides, dyes and plastics auxiliaries, e.g. for preparing polyimide molded bodies.
