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.

3-Amino-5-methyl-2,4-dicarbonitrile biphenyl derivatives 1-14 have been synthesized and all compounds were screened for their antibacterial effects against fourteen Gram-positive and sixteen Gram-negative bacterial strains and showed varying degree of activities. Compounds 1, 2, 4, 5, 6, 8, 13, and 14 were found to be significantly active against various Gram-positive bacteria, however, compounds 1
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.
