Abstract

7-amino-2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-triones were synthesized via the three-component condensation of luminol, dimedone, and aromatic aldehydes in EtOH at 80 °C for 9-15 min catalyzed by solid silica sulfuric acid (SSA) and the luminescence of products was studied in details.

Keywords: Phthalhydrazide, silica sulfuric acid (SSA), luminol, catalyst, synthesis, luminescence
