Synthesis of Substituted Benzothiophenes by Acid-Catalyzed Cyclization of Thiophenylacetals and Ketones
Benzothiophenes substituted at the 3 position with methyl or carboxymethyl and at the 5 position with methyl, methoxy, chloro, bromo and nitro were prepared by cyclization of thiophenyl-acetals and ketones using a suspension of polyphosphoric acid in refluxing chlorobenzene.The overall efficiency of this method is superior to literature procedures because of the lower temperature and the limited amount of PPA used.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.4923-87-9. In my other articles, you can also check out more blogs about 4923-87-9
