Abstract:
Die vorliegende Erfindung betrifft Hexaorganoguanidinium-organocarbonate gemäß Formel (I), ein Verfahren zu ihrer Herstellung sowie ihre Verwendung. Dabei stehen R1 bis R5 für Alkyl, AIIyI, Vinyl, Benzyl, Aryl oder Heteroaryl; wobei die Gruppen R 1 und R 2 , R 3 und R 4 oder R 2 und R 3 auch gemeinsam mit Stickstoffatomen des Guanidingerüstes cyclische sekundäre Aminogruppen bilden können R 6 steht für Alkyl, Benzyl oder AIIyI, und R 7 steht für Alkyl, Benzyl, AIIyI, Aryl oder Heteroaryl. Die erfindungsgemäßen Hexaorganoguanidinium-organocarbonate werden durch Umsetzung eines Pentaorganoguanidins mit einem Diorganocarbonat hergestellt, wobei die Reaktion in Lösung oder in der Gasphase durchgeführt werden kann. Das erfindungsgemäße Verfahren ist atomökonomisch und vermeidet die Bildung von Nebenprodukten. Die Hexaorganoguanidinium-organocarbonate können zur Herstellung anderer Hexaorganoguanidinium-Salze verwendet werden. Durch Reaktion mit einer Säure oder einem sauren Salz kommt es zur Anionen-Metathese unter Decarboxylierung des Organocarbonats. Dadurch wird das Reaktionsgleichgewicht auf die Produktseite verschoben. Sowohl die erfindungsgemäßen Hexaorganoguanidinium-organocarbonate als auch die aus ihnen erhältlichen Hexao ganoguanidiniumsalze sind hochreine, insbesondere halogenidfreie, ionische Flüssigkeiten.
Abstract:
