A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 930-88-1, Name is 1-Methyl-1H-pyrrole-2,5-dione, molecular formula is C5H5NO2. In an article, author is Gein, L. F.,once mentioned of 930-88-1, Formula: C5H5NO2.
Reaction of 5-aryl-4-acetyl-3-hydroxy-1-(omega-carboxyalkyl)-3-pyrrolin-2-ones with aromatic amines
Reactions of 5-aryl-4-acetyl-3-hydroxy-1-(omega-carboxyalkyl)-3-pyrrolin-2-ones with aromatic amines led to the formation of 5-aryl-4-(1-arylaminoethylidene)-1-(omega-carboxyalkyl)pyrrolidine-2,3-diones whose structure was confirmed by IR and (1)H NMR spectra and XRD analysis.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 930-88-1, you can contact me at any time and look forward to more communication. Formula: C5H5NO2.
