The first metal‐free catalysts are reported for the methylation of amines with carbon dioxide. Proazaphosphatrane superbases prove to be highly active catalysts in the reductive functionalization of CO2, in the presence of hydroboranes. The new methodology enables the methylation of NH bonds in a wide variety of amines, including secondary amines, with increased chemoselectivity.
Eine neuartige Methode setzt auf CO2 als Kohlenstoffquelle bei der Methylierung von Aminen mit Wasser als Nebenprodukt. Diese Strategie ermöglicht eine nachhaltige Herstellung von Methylaminen durch Umwandlung von CO2 zu hochwertigen Chemikalien mithilfe molekularen Wasserstoffs als preiswertes und erneuerbares Reduktionsmittel. Die Methode könnte neuartige Anwendungen für die Wiederaufbereitung von...
