Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, the author is Etzbach, Karl-Heinz and a compound is mentioned, 1193-54-0, 3,4-Dichloro-1H-pyrrole-2,5-dione, introducing its new discovery. 1193-54-0
Synthesis of Five-Membered Heterocycles from Maleimides
New heterocycles containing maleimide building blocks were prepared via 2-chloro-3-cyanomaleimide or 2,3-dichloromaleimides as key intermediates.Of the heterocyclic amines thus prepared, the following systems are useful as diazo components for preparing disperse dyes: 5-aminopyrazole-3,4-dicarboximides 5, 4-amino-5-alkoxycarbonylthiophene-2,3-dicarboximides 7, 5-aminoisothiazole-3,4-dicarboximides 9, 5-aminoisothiazole-3,4-dicarboxamide (10), 5-amino-3,4-dicyanoisothiazole (12), 5-amino-4-cyanothiophene-2,3-dicarboximides 15, and 2-aminothiazole-4,5-dicarboximides 17.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 214894-89-0!, 1193-54-0
