Pd/RHA and Pd/BPA as Eco-Friendly Heterogeneous Catalysts: Microwave-Assisted C-S Cross-Coupling Reaction in DMF

First time, Pd-Rice Husk Ash (Pd/RHA) and Pd-Banana Peel Ash (Pd-BPA) were used as eco-friendly catalysts in the C-S cross-coupling reaction of 5-bromo-2,1,3-benzothiadiazole with various benzene thiols in DMF under microwave irradiation at 75 degrees C, 200 W (100 psi) for 15-25 min. These catalysts were produced from agro-industrial wastes, such as rice husk ash and banana peel ash. These can be recycled and reused up to five catalytic cycles without loss of catalytic efficiency.

Automated summary

In this study, Pd-Rice Husk Ash and Pd-Banana Peel Ash were used as eco-friendly catalysts for the C-S cross-coupling reaction of 5-bromo-2,1,3-benzothiadiazole with various benzene thiols. These catalysts, derived from agro-industrial wastes, showed excellent recyclability without loss of catalytic efficiency.
