Abstract: 1419074 Preparation of 2-amino-3,5-dinitrothiophenes IMPERIAL CHEMICAL INDUSTRIES Ltd 9 May 1973 [9 June 1972 29 Aug 1972] 27005/72 and 39948/72 Heading C2C 2 - Amino - 3,5 - dinitro-thiophenes of Formula I wherein R is a hydrogen atom or a hydrocarbon radical, which, if an aralkyl or aryl radical, may be substituted in the aryl ring by one or more nitro groups introduced in the course of the preparation, are obtained by decarboxylating and dinitrating a compound of Formula II and finally hydrolysing off the acyl group. The compound of Formula II may be decarboxylated prior to the dinitration (e.g. by heating in a basic solvent at between 170‹ and 230‹ C.), or one of the nitro groups can be introduced in the 5-position followed by decarboxylation and introduction of the 3-NO 2  group, or the decarboxylation can be effected simultaneously with the dinitration (e.g. by HNO 3 /H 2 SO 4  at -20‹ to + 30‹ C. using at least 2 mols of HNO 3  per mol. of II). Specified acyl groups are formyl, acetyl, propionyl, benzoyl, methyl sulphonyl, chloroacetyl, #-carboxypropionyl and p-toluene sulphonyl and the final hydrolysis of the acyl group is preferably effected by an aqueous or alcoholic solution of a mineral acid (e.g. H 2 SO 4  at #100‹ C.). The starting materials of Formula II are themselves obtained by treating a compound of Formula III with cyanoacetic acid, an alkyl cyanoacetate or cyanoacetamide in aqueous alkaline medium and then acrylating the resulting product at a pH between 4 and 10. Examples describe the preparation of 2- amino-3,5-dinitrothiophenes wherein R is -H, -CH 3 , or phenyl and many intermediates as well as starting materials of Formulµ II and III are isolated. The compounds of Formula I are used as the diazo components of disperse monoazo dyestuffs.
