The Synthesis of 2,11-Diamino-4,9-diphenyl-4,9-dihydrobenzo [f] pyrano[3,2-h]chromene-3,10-dicarbonitrile Derivatives using Triethanolammonium Acetate as a Green Ionic Liquid
Triethanolammoniumacetate [TEA][HOAc] was used as a greenionicliquid 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
