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
new environmental benign method for synthesis of phenothiazine derivatives using microwave irradiation has reported. A mixture of o-substituted aromatic amine and p-substituted phenol converted into biphenyl amine derivative using microwave irradiation. Further, thionation of biphenyl amines under same irradiation has provided the title phenothiazine derivatives. The later compounds then oxidized to
