Low viscosity ionic liquids based on organic salts of the dicyanamide anion

New families of salts viz. quaternary ammonium, N-alkyl-N-methylpyrrolidinium or 1-alkyl-3-methylimidazolium dicyanamides, Cat(+)N(CN)(2)(-), are low melting compounds, most being liquid at rt, water-miscible and have low (for ionic liquids) viscosity at rt, e.g. eta = 21 cP for 1-ethyl-3-methylimidazolium dicyanamide.
