摘要
In this article, the same reaction of aromatic aldehyde, malononitrile, and 2-(2,3-dihydrochromen-4-ylidene) malononitrile was performed in ionic liquids of [BMIm]BF4 and [BMIm]Br, resulting in a green synthesis of 6H-benzo[c]chromene-8,8,10(7H)-tricarbonitrile and 6H-benzo[c] chromene-8,10-dicarbonitrile derivatives in good yields. This procedure has the advantages of good yields, one pot, and environmental friendliness.
