Abstract Green solvents such as deep eutectic solvents are new emerging alternatives to the conventional harmful organic solvents which may find a number of interesting applications in industrial and chemical processes. A facile, atom-economic and environmentally-benign one-pot reaction of salicylaldehyde and malononitrile with various nucleophiles, including indoles, thiols, secondary amines, cyanide and azide were efficiently achieved in choline ...
