| titleOfInvention | Substituted trifluoromethoxy- and trifluoromethylmercaptophenothiazines |
| abstract | The invention comprises compounds having the formula : <FORM:0851952/IV(b)/1> in which Y is oxygen or sulphur. These compounds may be obtained by heating a substituted diphenylamine with sulphur. Alternatively they may be obtained by the cyclisation of substituted diphenyl sulphides. e.g. 21-bromo-2-amino-4-trifluoromethoxydiphenyl sulphide. Examples describe the preparation of 2-trifluoromethylmercaptophenothiazine and 2-trifluoromethoxyphenothiazine. 3-bromophenyltrichloro-methyl sulphide is obtained by contacting 3-bromophenylsulphide with dry chlorine. 3-trifluoromethyl mercapto diphenyl amines are obtained by treating 3-bromophenyl trichloromethyl sulphide with SbF3 to give 3-bromophenyl trifluoromethyl sulphide which is reacted with acetanilide. 21-bromo-2-amino-4-trifluoromethoxy diphenyl sulphide is obtained by condensing 3- nitro-4-chlorophenyl trifluoromethyl ether with o-bromothiophenol to obtain 21-bromo-2-nitro-4-trifluoromethoxydiphenyl sulphide which is reduced. |
