Shimojo, Hiroyuki et al. published their research in Synthesis in 2013 | CAS: 55219-11-9

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. It is found within the chemical structures of pharmaceutical drugs such as zileuton, raloxifene, and sertaconazole, and also BTCP.COA of Formula: C9H5NS

Simple one-pot conversion of alcohols into nitriles was written by Shimojo, Hiroyuki;Moriyama, Katsuhiko;Togo, Hideo. And the article was included in Synthesis in 2013.COA of Formula: C9H5NS This article mentions the following:

Various benzylic and primary alcs. were efficiently converted into the corresponding nitriles in good yields at room temperature by treatment with Me3COCl, I2, or 1,3-diiodo-5,5-dimethylhydantoin in the presence of TEMPO, followed by treatment with I2 and aqueous NH3. The nitriles were obtained in good yields and high purities simply by extraction of the reaction mixture with CHCl3 and subsequent removal of the solvent. In the experiment, the researchers used many compounds, for example, Benzo[b]thiophene-2-carbonitrile (cas: 55219-11-9COA of Formula: C9H5NS).
