4923-87-9, Chemical Research Letters, May 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In a article, 4923-87-9, molcular formula is C8H5BrS, introducing its new discovery.
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
