A simple, efficient, and cost‐effective method for the synthesis of 2__H__‐indazolo[2,1‐b]phthalazine‐1,6,11(13__H__)‐trione derivatives by a one‐pot, three‐component condensation reaction of phthalazide, dimedone, or 1,3‐cyclohexanedione and aromatic aldehydes under CH~3~CN/DMF (8:2) media at 80°C for 30–60 min in the presence of trimethylsilyl chloride (TMSCl) is described. J. Heterocyclic Chem., (2009).

## Abstract Phosphomolybdic acid (PMA)–SiO~2~ was found to be an efficient catalyst for the three‐component condensation reaction of phthalhydrazide, 1,3‐diketone, and aldehydes to produce 2__H__‐indazolo[1,2‐__b__]phthalazine‐triones in excellent yields. The catalyst can be recovered and reused wi
