The synthesis of some fluorescent 2,6‐dicyano‐3,5‐disubstituted anilines using cellulose sulfuricacid (Cellulose‐SA) as an environmentally benign catalyst in H2O is described. The one‐pot reaction of 1,3‐diketone and three equiv. of malononitrile was carried out in the presence of one equiv. of a secondary amine, Cellulose‐SA as catalyst, and H2O as solvent. The photophysical properties (λAbs., λFlu

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.

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

Abstract A pseudo-five-component reaction leading to efficient synthesis of dicyanoanillines was developed using only aromaticaldehydes and malononitrile as the starting reactants. Mechanistic studies suggested that a malononitrile dimer and the Knoevenagel condensation product of benzaldehyde, initially formed in the reaction mixture, combine with a fourth equivalent of malononitrile to form the
