Solvent-free anhydrous Li+, Na+ and K+ salts of [B(3,5-(CF3)2C6H3)4]−, [BArF4]−. Improved synthesis and solid-state structures†
A modified, convenient, preparation of solvent-free, anhydrous, Li+, Na+ and K+ salts of the ubiquitous [BArF4]− anion is reported, that involves a simple additional recrystallisation step. Anhydrous Na[BArF4], K[BArF4], and [Li(H2O)][BArF4], were characterised by single-crystal X-ray diffraction.
