In Situ Decorated Palladium Nanoparticles on Chitosan Beads as a Catalyst for Coupling Reactions

A green protocol for the in situ synthesis of Pd nanoparticles on chitosan beads (Pd NPs-CS) is reported without need to use any toxic reducing agents. The preparation catalyst was performed using a simple coordination reaction between prepared and palladium ions NPs-CS). obtained characterized by different techniques, including SEM, EDX, DRX, FTIR analyses. NPs-CS investigated Suzuki–Miyaura cross-coupling Heck under greener conditions, results show high catalytic activity selectivity. bead form easily separated from mixture obtain desired products, as confirmed spectroscopic methods. This sustainable has advantages having organic reactions such biopolymer support recovery significant loss or
