C-C and C-H coupling reactions by Fe 3 O 4 /KCC-1/APTPOSS supported palladium-salen-bridged ionic networks as a reusable catalyst.

This study investigates the potential application of an efficient, easily recoverable and reusable magnetically separable Fe 3 O 4 /KCC-1/APTPOSS nanoparticle-supported salen/Pd(ii) catalyst for C-C and C-H cross-couplings. The Fe 3 O 4 /KCC-1/APTPOSS/salen/Pd(ii) MNPs were thoroughly characterized by using TEM, FE-SEM, TGA, XRD, VSM, FT-IR, ICP-MS, and BET. This observation was exploited in the direct and selective chemical reaction of 2-acetyl-benzaldehyde with cyclopentadiene for the synthesis of pentafulvene. The recycled catalyst has been analyzed by ICP-MS showing only minor changes in the morphology after the reaction, thus confirming the robustness of the catalyst.
