Reference of 19064-65-4, 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, 19064-65-4, molcular formula is C5H6N2O, introducing its new discovery.
Photolysis of pyridazin-3-one 1-imides: Ring contraction into 3-pyrrolin-2-one derivatives
Irradiation of pyridazin-3-one l-ethoxycarbonylimide (9a) resulted in ring contraction to give the azamaleimide (11), whereas the 6-methyl derivative (9b), upon irradiation, afforded the 3-pyrrolin-2-one (12). On the other hand, the photolysis of 2-methylpyridazin-3-one 1-imides (10a,b) gave both azamaleimides (13a, b) and 3-pyrrolin-2-ones (14a, b). The mechanism of this photo-induced ring concentration reaction is discussed.
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 19064-65-4 is helpful to your research. Reference of 19064-65-4
