Synthesis and Application of Nano Vanadium‐Oxo Pyridiniumporphyrazinato Sulfonic Acid for Synthesizing Pyrazole and Dihydropyrano [2,3] pyrazole Derivatives
ChemistrySelect Vol. 7, No. 29
چکیده
Abstract In this study, we presented a description of designing and synthesizing an original nano‐N‐sulfonated (‐SO 3 H) phthalocyanine molten salt (vanadium‐oxo pyridiniumporphyrazinato sulfonic acid) [VO(TPPASO 3 H)]Cl as a recyclable and efficient heterogeneous catalyst with thermal stability for synthesizing pyrazole and dihydropyrano [2,3] pyrazole derivatives. After recycling and reapplying five times, this catalyst indicated no significant decrease in the catalytic activity.
