| titleOfInvention | Method for the preparation of 2-alkyl substituted thiazoles and selenazoles |
| abstract | 1319959 Fused thiazoles and selenazoles AGFA-GEVAERT 27 Oct 1970 [3 Nov 1969] 53824/69 Heading C2C 2 - Alkyl - benzothiazoles, naphthothiazoles, benzoselenazoles and naphthoselenazoles, the benzenoid rings optionally having further substituents, are prepared by catalytic hydrogenation of a bis-2-nitro-or-amino-phenyl or naphthyl-disulphide or diselenide in the presence of an alkane carboxylic acid anhydride using as catalyst a rhenium sulphide, followed if desired by hydrolysis of any carboxylic ester or amide groups formed by acylation during the reaction. Bis - 2 - nitrophenyl and 2 - nitro naphthyl disulphides, optionally having further substituents, are prepared by reaction of sodium disulphide with a 2-nitroaryl chloride. Bis-2-nitrophenyl-selenides, optionally having further substituents, are prepared by reaction of a 2-nitrophenylselenocyanide with potassium hydroxide. Bis-2-aminophenyl-disulphide is prepared by reaction of o-nitro-chlorobenzene with sodium disulphide, followed by reaction with hydrogen peroxide. |
