Low melting and slightly viscous ionic liquids via protonation of trialkylamines by perfluoroalkyl β-diketones
摘要:
New trialkylammonium perfluoroalkyl beta-diketonate salts are obtained in one-step reactions by taking advantage of proton transfer from perfluoroalkyl beta-diketones to tertiary amines. The charge associated with the beta-diketonate anion is considerably delocalized, which may play a role in giving rise to low melting and thermally stable salts with low viscosities and densities.
