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).

This study reports a series of benzo[b]thiophene (BT) derivatives with good electronic properties as host materials for red phosphorescent organic light-emitting diodes (PHOLEDs). We applied thermally-stable materials for red PHOLEDs which contain BT and carbazole moieties which also provide a good charge transport ability, as well as a good charge confinement effect (T₁ > 2.25 eV). To control the appropriate charge transporting ability, two different structures having one or two carbazole units connected to the single BT moiety were prepared Using this approach, we found that the material with a single carbazole and a single BT unit showed the best current efficiency and external quantum efficiency (up to 23.6 cd/A and 12.8%, resp.). The results of the experiment also suggest that BT could be used as an electron-transporting unit when utilized with carbazole moiety, although it has previously been utilized as a p-type material.
