Ring-Opening Reactions of Nonactivated Aziridines Catalyzed by Tris(pentafluorophenyl)borane
摘要:
The ring-opening reactions of nonactivated aziridines with amine nucleophiles are efficiently catalyzed by tris(pentafluorophenyl)borane leading to derivatives of trans- 1,2-diamines in high yields. A mechanistic investigation of the reaction suggests that in situ formed [(C6F5)(3)B(OH2)].H2O catalyzes the opening through a Bronsted acid manifold.
