The syntheses of fluorinated phenothiazines and fluorinated 1,4-benzothiazines are reported.Fluorinated phenothiazines have been prepared via a Smiles rearrangement of N-formylateddiphenylsulphides, synthesized in turn by condensation of substituted 2-aminobenzenethiolswith 2-chloro-5-trifluoromethylnitrobenzene followed by formylation with formic acid.Fluorinated 4H-1,4-benzothiazines have been prepared
报道了氟化吩噻嗪和氟化1,4-苯并噻嗪的合成。氟化吩噻嗪是通过N-甲酰化二苯基硫化物的Smiles重排制备的,该取代反应是将取代的2-氨基苯硫醇与2-氯-5-三氟甲基硝基苯缩合,然后与甲酰化反应合成的。氟化的4 H -1,4-苯并噻嗪是通过将取代的2-氨基苯硫醇与对氟苯甲酰基丙酮在DMSO中进行缩合和氧化环化反应制得的。该反应被认为是通过烯氨基酮系统进行的。包括IR和NMR光谱研究。
