以苯并恶二唑和二芳基碘鎓盐为原料，实现了铜催化的吩嗪N-氧化物的区域选择性合成。该过程是由苯并恶二唑与二芳基碘鎓盐的亲电芳基化反应和随后的苯并环化反应引发的。氮氧化物原位还原为吩嗪支架和偏离有机荧光材料很容易实现。
The Cu-catalyzed regioselective synthesis of phenazineN-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 ofN-oxides in situ to phenazine scaffolds and deviation to organic fluorescent materials were readily accomplished.
