Molecular iodine in the presence of potassium carbonate has been found to be an efficient and eco-friendly catalyst for the synthesis of polysubstituted dicyanoanilines from aldehydes, acetone and malononitrile under solvent-free thermal condition. The experimental procedure is simple, includes shorter reaction times (less than 10 min) and results in excellent yield of the products.

Abstract A convenient, environmentally friendly, and solvent‐free procedure has been developed for the synthesis of 3‐amino‐2,4‐dicarbonitrile‐5‐methylbiphenyl derivatives. Compared with the classical reaction condition, this new synthetic method has the advantages of excellent yields, easy setup, mild reaction conditions, and environmental friendlines.

A Novel Synthesis of 3-Aryl-2,6-dicyano-5-methylanilines via Reaction between Nitrostyrenes and Malononitrile
A novel and simple synthesis of 3-aryl-2,6-dicyano-5-methylanilines is described. Reactions between nitrostyrenes and excess malononitrile in the presence of sodium carbonate in 80% ethanol proceeded at room temperature to afford the aromatic products in good yields. A mechanism for the formation of the products is proposed.
