Chemical Research Letters, May 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.category: benzothiophene, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 4923-87-9, Name is 5-Bromobenzothiophene, molecular formula is C8H5BrS
1,1?-Bi(hetero)aryl 2-sulfonamide scaffolds have been widely used as a privileged structure in drug discovery. Herein, we report an efficient rhodium-catalyzed oxidative C-H/C-H cross-coupling between a (hetero)aromatic sulfonamide and a (hetero)arene to afford ortho-sulfonamido bi(hetero)aryls. This methodology features broad substrate scope, good functional group tolerance, and relatively inexpensive catalyst (without the use of RhCp). A wide range of (hetero)arenes such as thiophenes, benzothiophenes, pyrroles, furans, benzofuran, indolizine, and simple arenes can engage in this transformation. This protocol also provides a facile route to bi(hetero)aryl sultams and dibenzo[b,d]thiophene 5,5-dioxides through further intramolecular cyclization, indicating its potential application in materials exploitation.
In the meantime we’ve collected together some recent articles in this area about 4923-87-9 to whet your appetite. Happy reading!category: benzothiophene
