Abstract
Steric factors have been shown to be responsible for the anomalous dehydration of 2-phenylindole-3-carboxamide (1) to 2-phenylindole-3-carbonitrile (3) by lithium aluminum hydride. This steric effect was also reflected in the reactions of 2-phenylindole (4) and its derivatives.
Zusammenfassung
Es wird gezeigt, daß für die anomale Dehydratisierung von 2-Phenylindol-3-carbonsäureamid (1) zum entsprechenden Nitril3 durch Lithiumaluminiumhydrid sterische Faktoren verantwortlich sind. Dieser sterische Effekt zeigt sich auch bei Reaktionen von 2-Phenylindol (4) und seiner Derivate.
