Microwave assisted synthesis of biarlys by CC coupling reactions with a new chitosan supported Pd(II) catalyst

• High TON and TOF value recorded for chitosan supported Pd(II) catalyst.
• This catalyst showed a better performance in Suzuki CC coupling reactions.
• Synthesis of biarlys under MW at 4 min was succeeded.

In this study a new type chitosan-based support has been produced for Pd(II) catalyst and its catalytic performance in Suzuki CC reactions has been studied under microwave irradiation without using any solvent. The chemical identification of the catalyst was performed using TG/DTG, FTIR, UV–Vis ICP-OES, SEM/EDAX, 13C NMR, molar conductivity, XRD and magnetic moment techniques. The performance of this new Pd(II) catalyst was studied in Suzuki CC reactions. The Pd(II) catalyst exhibited a good catalytic performance in very short time (4 min) by giving high TONs and TOFs with low amount of the catalyst (0.015 mol%). The catalyst also had reusability and did not lose its activity until six runs.
