摘要

A new piperazine-based dicationic Bronsted acidic ionic salt named as piperazine-1,4-diium dihydrogen phosphate was prepared. After characterization by FT-IR, Mass and NMR spectroscopy, it was used as an efficient and reusable catalyst for the synthesis of 5-arylidenepyrimidine-2,4,6(1H,3H,5H)-trione and pyrano[2,3-d]pyrimidinone (thione) derivatives. Some of the advantages of this method are utilization of low amount of the catalyst, ease of work-up, short reaction times, excellent yields and acceptable reusability of the catalyst.
