1-Butyl-2,3-Dimethyl-Imidazolium (bdmim) Cation

Due to the absence of the 2-H proton, ionic liquids based on the 1-butyl-2,3-dimethyl-imidazolium (bdmim) cation display lower polarity and hydrogen bond donnor ability than their bmim counterparts. They are also somewhat more viscous and don't form carbenes under basic conditions.
Viscosity: Cl^- (solid at rt) > PF₆^- > BF₄^- > Tf₂N^-
Polarity: Cl^- > BF₄^- > PF₆^- > Tf₂N^-
[bdmim][PF6] and [bdmim][Tf2N] have low solubility in water at rt.
