Anwendungen & Verwendung

Verwenden

Azetidine is involved in a high yielding palladium-catalyzed cross-coupling reaction with aryl bromides. Further, it is used in Ullmann type coupling reaction with iodonitroflourenes. In addition to this, it reacts with bis-(3-amino-propyl)-amine to prepare N,N'-bis-(3-amino-propyl)-propanediyldiamine using palladium as a catalyst.
