A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Product Details of 1941-30-6, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1941-30-6, Name is Tetrapropylammonium bromide, molecular formula is C12H28BrN. In a Article, authors is Etivand, Nasser，once mentioned of 1941-30-6
Abstract: A convenient, regioselective, novel, and elegant one-pot, four-component reaction was designed for synthesis of a series of new of imidazo[1,2-a]pyridines using aryl glyoxal monohydrates, ethyl acetoacetate, hydrazine hydrate, and 2-aminopyridine in presence of tetrapropylammonium bromide under reflux in EtOH as solvent. The main advantages of this protocol include the availability and low cost of the starting materials, short reaction time, convenient operation, easy workup process, highly facile operation, nonhazardous byproducts, and high yield (82?94%).
