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, 13104-56-8, name is 4′-(4-Methoxyphenyl)-2,2′:6′,2”-terpyridine, introducing its new discovery. Quality Control of: 4′-(4-Methoxyphenyl)-2,2′:6′,2”-terpyridine
The catalytic system involving Sc(OTf)3 and a dendritic terpyridine ligand is able to promote the Friedel-Crafts acylation of a wide range of aromatics under microwave irradiation. The expected products are obtained in high yields after short reaction times and the nano-sized catalyst can be recovered and successfully used in 12 consecutive runs.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13104-56-8 is helpful to your research. Quality Control of: 4′-(4-Methoxyphenyl)-2,2′:6′,2”-terpyridine
