New Advances in Chemical Research in 2021. In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 148231-12-3, name is 5,8-Dibromoquinoxaline, introducing its new discovery. Reference of 148231-12-3
Two bis-BN phenanthrenes have been synthesized. Their photophysical properties are different from those of the reported mono-BN phenanthrenes. Moreover, the stepwise bromination of bis-BN phenanthrene 8 gave a series of brominated bis-BN phenanthrenes, with all of the mono-, di-, tri-, and tetrabrominated bis-BN phenanthrenes being successfully isolated and characterized. In addition, preliminary results showed that mono- and dibrominated species can be further functionalized by cross-coupling reactions.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 148231-12-3
