New Advances in Chemical Research in 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, new energy materials, preparation and modification of special coatings. Application In Synthesis of 5-Bromobenzothiophene. Introducing a new discovery about 4923-87-9, Name is 5-Bromobenzothiophene
A sequential cross-coupling/annulation of ortho-vinyl bromobenzenes with aromatic bromides was realized, providing a direct and modular approach to access polycyclic aromatic compounds. A vinyl-coordinated palladacycle was proposed as the key intermediate for this sequential process. Excellent chemoselectivity and regioselectivity were observed in this transformation. The practicability of this method is highlighted by its broad substrate scope, excellent functional group tolerance, and rich transformations associated with the obtained products.
