Abstract
Biopolymers were used as supports for the preparation of palladium-based nanoparticles (pd- NPs). The chitosan-based Pd (II) catalyst (non-toxic, cheap, eco-friendly) were structurally characterized using a range of methods such as Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), Differential scanning calorimetry (DSC), Differential thermal analysis (DTA), Xray photoelectron spectroscopy (XPS ), transmission electron microscopy
(TEM), scanning electron microscopy (SEM).( Fig 1,2) palladium is commonly known as best catalyst in the Suzuki–Miyaura coupling reactions due to its very high efficiency therefore, using the recently chitosanbased Pd (II) catalyst in the Suzuki–Miyaura coupling reactions, will be described. The reaction optimization and substrate scope will be discussed, and role of rapid catalyst activation in achieving mild reaction conditions will be emphasized.

Audience Take Away:
- I think the audience will surely get benefited by the work presented herein as the methodology developed is quite simple, advantageous and easy to handle.
- The researchers will be able, after my talk, do their own catalyst preparation using similar method.
- The different applications in industry, medicine and ecology will be discussed.
- The chitosan-based Pd (II) catalyst can be applied to Suzuki–Miyaura coupling reactions.
