crucial encumbrance for the synthesis of squaramides through nucleophilic substitution of squaric acid. The reactions must be performed in an aqueous medium since squaric acid is insoluble in virtually all organic solvents. The scope of amine nucleophiles was consequently restricted to those amines soluble in water. Owing to remarkable solvating ability of ionicliquid, reactions of squaric acid with
