IKHILE, Monisola I.; BALA, Muhammad D. y NYAMORI, Vincent O.. A greener method towards the synthesis of 1,3-diarylimidazolium tetrafluoroborates. S.Afr.j.chem. (Online) [online]. 2011, vol.64, pp.101-104. ISSN 1996-840X.
A new strategic method for the synthesis of 1,3-diarylimidazolium tetrafluoroborate salts is illustrated herein. A solvent-free approach was employed in the synthesis of the diimines which are precursors in the preparation of the imidazolium salts. The reaction proceeds faster, cleaner and in a better yield than previously reported methods.
