Nv. Moskalev et al., NEW REACTION OF MONONITROARENES - CONDENSATION WITH 2 ACETOPHENONE MOLECULES VIA THE NITRO-GROUP, Russian chemical bulletin, 45(2), 1996, pp. 462-464
Nitrobenzene, p-bromonitrobenzene, N,N-diethyl-p-nitroaniline, and 9-m
ethyl-3-nitrocarbazole undergo condensation with two moles of acetophe
none in a DMSO-KOH system to form the corresponding (Z)-1,4-diphenyl-2
-arylamino-2-butene-1,4-diones.
