Solvent-free synthesis of 2H-indazolo[2,1-b] phthalazine-triones promoted by cavitational phenomenon using iodine as catalyst Varghese, Anitha Nizam, Aatika Kulkarni, Rajani George, Louis Iodine Dimedone Phthalhydrazide Aromatic aldehydes Cavitational chemistry 2H-Indazolo[2 1-b]phthalazine-triones An environmentally benign, simple and efficient protocol for the synthesis of 2H-indazolo[2,1-b] phthalazine-triones by condensation of phthalhydrazide, aromatic aldehydes and dimedone under solvent-free ultrasound assisted conditions employing a safe, readily available iodine as catalyst has been described. This process is a valuable addition as it devoids the use of any solvent and takes place in short duration of time giving good yield of the products.
