Abstract

Phosphomolybdic acid PMA–SiO2was found to be an efficient catalyst for the threecomponent condensation reaction of phthalhydrazide, 1,3diketone, and aldehydes to produce 2Hindazolo1,2bphthalazinetriones in excellent yields. The catalyst can be recovered and reused without significant loss of activity. [ABSTRACT FROM AUTHOR]
