Synthesis of the title compounds by the Smiles rearrangement has been reported. 1-Nitrophenothiazines have been prepared by the reaction of 2-amino-3-chloro/methyl/methoxythiophenol with substituted o-halonitrobenzenes in ethanolic sodium hydroxide, in which Smiles rearrangement occurs in situ. 1-chloro/methyl-7-substituted phenothiazines have been prepared by Smiles rearrangement of 3-chloro/meth
已经报道了通过Smiles重排合成标题化合物的方法。1-硝基吩噻嗪是由2-氨基-3-氯/甲基/甲氧基硫代苯酚与取代的邻卤代硝基苯在乙醇氢氧化钠中反应制得的,其中微笑发生在原位。1-氯/甲基-7-取代的吩噻嗪已经通过3-氯/甲基-2-甲酰胺基2'-硝基-4'-取代的二苯硫醚的Smiles重排制备。后者是通过将2-氨基-3-氯/甲硫基苯酚与取代的邻卤代硝基苯在乙醇乙酸钠中缩合而制得的二苯硫醚的甲酰化制得。光谱研究也包括在内。
