چکیده	In this study, we presented a description of designing and synthesizing an original nano‐N‐sulfonated (‐SO3H) phthalocyanine molten salt (vanadium‐oxo pyridiniumporphyrazinato sulfonic acid) [VO(TPPASO3H)]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.
