Article Preview

A simple and efficient one-pot method for the preparation of 2H-indazolo [2,1-b] phthalazine-triones from phthalhydrazide, dimedone and aromatic aldehydes has been developed using ionic liquids as catalysts. Two ionic liquid catalysts are described, and the ionic liquid [(CH2)4SO3HMIM]HSO4 catalyst is found to be more effective than [HMIM]HSO4 for this condensation reaction.
