Chlorometallate(III) ionic liquids as Lewis acidic catalysts – a quantitative study of acceptor properties

Author affiliations

Abstract

The Gutmann Acceptor Number (AN), which is a quantitative measure of Lewis acidity, has been estimated using the 31P NMR chemical shift of a probe molecule, triethylphosphine oxide, for a range of chlorometallate(III) ionic liquids, based on Group 13 metals (aluminium(III), gallium(III) and indium(III)) and the 1-octyl-3-methylimidazolium cation, at different compositions. The results were interpreted in terms of extant speciation studies of chlorometallate(III) ionic liquids, and compared with a range of standard molecular solvents and acids. The value of these data were illustrated in terms of the selection of appropriate ionic liquids for specific applications.
