Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 1072-63-5, Name is 1-Vinyl-1H-imidazole, SMILES is C=CN1C=CN=C1, belongs to imidazoles-derivatives compound. In a document, author is Ek, F, introduce the new discover, Quality Control of 1-Vinyl-1H-imidazole.
Synthesis of fused tetrazole- and imidazole derivatives via iodocyclization
The possibility to prepare fused tetrazole- and imidazole derivatives by iodocyclization in moderate to excellent yields is demonstrated. In some examples the cyclizations were not following Baldwin’s rules entirely, i.e. exo-selectivity. Nucleophilic substitution of the formed iodides gave different results depending on the hardness of the nucleophile. Thus, elimination of the iodide could be a problem but a substitution reaction with ethyl potassium xanthate and a radical reaction using acrylonitrile were tolerated. In addition, we showed that it is possible to selectively use three iodo substituents individually in one of the fused imidazole derivatives. (C) 2003 Elsevier Ltd. All rights reserved.
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 1072-63-5 is helpful to your research. Quality Control of 1-Vinyl-1H-imidazole.
