摘要

Present work describes the preparation, characterization, and catalytic applications of Sawdust–APTS–Pd for the Suzuki–Miyaura cross-coupling reaction. During the preparation of the catalyst, APTS was covalently grafted on a tremendous amount of –OH groups of sawdust and then reacted with Pd(OAc)2. Physical characterization of the prepared catalyst by EDX, XRD, SEM, FT-IR, and solid-state CP-MAS 13C-NMR showed a significant influence of both grafting of APTS and palladium loading on surface areas. The performance of this heterogeneous catalytic system is then reported for the Suzuki–Miyaura cross-coupling reaction. Ash of Pomegranate Peel (APP) has been used as a base to enhance the green character of the protocol. The robustness of the catalyst allowed five reuses to afford various biaryl derivatives with no significant loss in activity.
