Triethanolammonium acetate [TEA][HOAc] was used as a green ionic liquid and successfully utilized for the multi-component synthesis of 2,11-diamino-4,9-diphenyl-4,9-dihydrobenzo[f]pyrano[3,2-h]chromene-3,10-dicarbonitrile derivatives as new compounds by the reaction of 2,3-naphthalenediol with malononitrile and various aldehydes. Mild reaction conditions and high yields are some of the advantages of this method. These compounds were identified by IR, NMR spectroscopy and mass analysis.
