Supported Palladium Catalysis Using a Biguanide N-Donor Motif on Mesoporous Silica for Suzuki-Miyaura Coupling Reaction

Abstract

A supported Pd(II)/biguanide complex on ordered mesoporous SBA-15 material (Pd@SBA-15/Met) exhibited catalytic activity in the cross-coupling reaction. The structural and surface characteristics of the prepared catalysts were investigated by various techniques (XRD, SEM, FT-IR and AAS). The catalytic performance of the catalysts was evaluated in Suzuki-Miyaura coupling reaction and it was proved to act as a recoverable catalyst in green media with excellent reactivity combined with recyclability.
