Nano-Pd/Chitosan Composite: An Extremely Effective Catalyst to the Synthesis of Pyrazolyl Analogues through Suzuki–Miyaura Cross-Coupling Reactions in an Aqueous Medium

Substituted pyrazolyl derivatives were synthesized through Suzuki cross coupling of aromatic boronic acid with heterocyclic halide using newly nano-Pd/chitosan catalyst by the water-mediated green synthesis methodology. The reactivity nano-Pd was highly enhanced incorporating palladium nanoparticles a biopolymer chitosan matrix. studied thoroughly for its structure, morphology, and other fundamental aspects such as size shape various techniques including XRD, FESEM, EDAX analyses. scope disclosed their great stability remarkable reusability cross-coupling reaction twelve different acids under synthetic
