Electric Literature of 4971-56-6, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 4971-56-6, molcular formula is C4H4O3, introducing its new discovery.
A series of new N-substituted furo[3,4-b]quinoline derivatives were synthesized via a three-component reaction of an aldehyde, an enamineone and tetronic acid in glacial acetic acid under microwave irradiation without a catalyst. This new protocol has the advantages of shorter time, higher yields, lower cost and broader substrate scope, as well as easier operation.
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 4971-56-6 is helpful to your research. Electric Literature of 4971-56-6
