4923-87-9, Research speed reading in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 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.
In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to navigate research efforts intended to implement such knowledge in the development of new catalytic chemistries. Read on for other articles about 4923-87-9. 4923-87-9
