The buchwald–hartwig amination
http://www.name-reaction.com/buchwald-hartwig-amination 網頁An operationally simple mechanochemical method for the Pd catalysed Buchwald–Hartwig amination of arylhalides with secondary amines has been developed using a Pd PEPPSI catalyst system. The system is demonstrated on 30 substrates and applied in the context of a target synthesis.
