And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2019.Name: Benzo[b]thiophene-2-carbonitrile This article mentions the following:
Herein, a new means of activating aldoximes by an in situ generated thiocyanate radical from ammonium thiocyanate and mol. oxygen at room temp has been discussed. With a catalytic amount of organic dye aizenuranine as the photocatalyst, the dehydration of aldoximes proceeds smoothly under visible light irradiation, providing a simple to handle, excellent functional group tolerance, and metal-free protocol for a wide range of nitriles. In the experiment, the researchers used many compounds, for example, Benzo[b]thiophene-2-carbonitrile (cas: 55219-11-9Name: Benzo[b]thiophene-2-carbonitrile).
Benzo[b]thiophene-2-carbonitrile (cas: 55219-11-9) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The electrophilic substitution of benzothiophene systems is much less regioselective than that of indoles. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Name: Benzo[b]thiophene-2-carbonitrile
