Anodic cyanation of benzo[b]thiophenes was written by Yoshida, Kunihisa;Miyoshi, Kohji. And the article was included in Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) in 1992.COA of Formula: C9H5NS This article mentions the following:
The electrooxidation of benzo[b]thiophene and 2-methyl- and 3-methylbenzo[b]thiophene was carried out in methanol containing sodium cyanide at a Pt anode in a divided cell. In all instances, heterocyclic ring-substitution products were obtained, together with minor amounts of addition products. With methylbenzo[b]thiophene, a small amount of side-chain-methoxylation product was also formed as a byproduct. In the experiment, the researchers used many compounds, for example, Benzo[b]thiophene-2-carbonitrile (cas: 55219-11-9COA of Formula: C9H5NS).
Benzo[b]thiophene-2-carbonitrile (cas: 55219-11-9) 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. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.COA of Formula: C9H5NS
