چکیده
|
In this study, [h2-dabco][hso4]2 is applied as an acidic ionic liquid to exclude some disadvantages of former methods reported for the synthesis of 3-amino-1-aryl-1h-benzo[f]chromene-2-carbonitrile, 1-(benzothiazolylamino)phenylmethyl-2-naphthol, and 1-(benzoimidazolylamino)phenylmethyl-2-naphthol derivatives. in the presence of this catalyst, all reactions are performed under neat conditions during short reaction times in good-to-high yields. ease of preparation and recyclability of the catalyst are the other important advantages of this method.
