Ion-tagged pi-acidic alkene ligands promote Pd-catalysed allyl-aryl couplings in an ionic liquid

Abstract

Ionic pi-acidic alkene ligands based on chalcone and benzylidene acetone frameworks have been "doped" into ionic liquids to provide functional reaction media for Pd-catalysed cross-couplings of a cyclohexenyl carbonate with aryl siloxanes that allow simple product isolation, free from Pd (<50 ppm) and ligand contamination.
