Umsetzung von Phenylacetylen mit Aziden und Diazoverbindungen

subject

Chemistry Organic Chemistry Physical and Theoretical Chemistry Medicinal chemistry

description

Phenylazid und Benzylazid addieren sich an Phenylacetylen in sehr guter Ausbeute. Dabei entstehen 1.4- und 1.5-disubstituierte 1.2.3-Triazole in nahezu gleicher Menge. Diazomethan und Diazoessigester reagieren fast ausschlieslich zu 3(5)-substituierten Pyrazolen. Mit Diphenyldiazomethan und Diazofluoren findet wahrend der Reaktion Umlagerung zu trisubstituierten Pyrazolen statt.
