The Cu-catalyzed regioselective synthesis of phenazine N-oxides was realized from benzoxadiazoles and diaryliodonium salts. The process was initiated by the electrophilic arylation of benzoxadiazoles with diaryliodonium salts and followed by benzocyclization reactions. The further reduction of N-oxides in situ to phenazine scaffolds and deviation to organic fluorescent materials were readily accomplished.

The invention belongs to the technical field of chemical preparation of a polysubstituted phenazine derivative and its oxide high-efficient preparation method. The preparation method is added to the reactor in the diaryl expensive Iodized salt, benzo furazane, copper-based catalyst, replacing nitrogen after three times, adding solvent, finishing feeding the heating reaction; the end of the reaction, after cooling to room temperature after treatment, separating, purifying to obtain the phenazine oxide pure product; phenazine oxide product can be further reduction, after treatment, separation, purification phenazine derivatives. The present invention provides a multi-substituted phenazine derivative and its oxide process is reasonable, can be synthesized by other method is difficult to synthesis of the asymmetric multi-substituted phenazine derivatives, the preparation method is simple, high yield, the product is easy to purification.
