Reaction of halothianaphthenes with metal amides was written by Reinecke, Manfred G.;Hollingworth, T. A.. And the article was included in Journal of Organic Chemistry in 1972.SDS of cas: 6287-82-7 This article mentions the following:
2-Halothianaphthenes react with metal amides in liquid NH3 to give the 3-isomers which are stable under the reaction conditions. No amines or polyhalo compounds were detected. 2,3-Dibromothianaphthene is converted to 3-bromothianaphthene either with or without added thianaphthene. The former instance suggests an intermol. transhalogenation involving carbanions and the latter a dehalogenation via BrNH2. In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7SDS of cas: 6287-82-7).
2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. It is also used in the manufacturing of dyes such as thioindigo.SDS of cas: 6287-82-7
