Trans-Spanned Palladium Catalyst for Mild and Efficient Amination of Aryl Halides with Benzophenone Imine

A new protocol for palladium-catalyzed Buchwald-Hartwig amination of aryl chlorides and bromides with benzophenone imine as ammonia surrogate is described. The suggested reaction conditions are mild and may therefore be applied to a variety of sensitive starting materials.
