| چکیده مقاله |
| This research focuses on the rational design, synthesis, and application of ionic phthalocyanine-based catalysts. In this context, a zwitterionic vanadyl oxo tetrapyridinoporphyrazine catalyst, [VO(TPPACH₂CO₂H)]Cl, was successfully designed and synthesized, and its catalytic efficiency was evaluated in the synthesis of polyhydroquinoline and chromene derivatives. Subsequently, the ionic complex tetra-2,3- pyridiniumporphyrazinato cobalt tribromomethanide, [Co(TPPABr)]CBr₃, was prepared and effectively applied as a catalyst for the synthesis of henna-based compounds. Furthermore, tetra-3,2- pyridiniumporphyrazinato oxo vanadium tribromomethanide, [VO(TPPABr)]CBr₃, was synthesized and successfully employed as an efficient catalyst for the chemo- and homoselective oxidation of sulfides and benzylic alcohols. Metal phthalocyanines, as accessible and highly stable macrocyclic complexes, exhibit significant potential in catalytic applications [1,2]. The catalysts developed in this study demonstrated excellent catalytic performance and could be readily recovered and reused several times without noticeable loss of activity. Overall, this work provides a promising strategy for the design and development of taskspecific ionic phthalocyanines incorporating diverse counter-ion tags for various catalytic applications. |
