Simultaneous displacement of a nitro group during coupling of diazotized o-nitroaniline with phenols

During the diazo-coupling reaction, nucleophilic displacement of a nitro group was also observed. This was the main reaction (1→7) when the starting amine bore either a chlorine or methoxy group at the para position (1b-c). The newly prepared compounds (7) might serve as convenient building blocks in synthesis of some heterocycles. Versita Warsaw and Springer-Verlag Wien 2010.
