Abstract
|
A series of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones were obtained from aldehydes, phthalhydrazide and malononitrile in good to excellent yields at 80–100 C under solvent-free conditions by proceeding through a simple, mild and efficient procedure utilizingN,N,N0 ,N0 -tetrabromobenzene-1,3-disulfonamide [TBBDA] and poly(N-bromo-N-ethylbenzene-1,3-disulfonamide) [PBBS] as catalysts
