Palladium grafted dicarboxylic acid ligand supported on SBA-15 as an efficient catalyst for Suzuki- Miyaura reaction

The cross-coupling reactions of aryl halides with arylboronic acids, often referred to Suzuki-Miyaura coupling reactions, are versatile methods for synthesizing unsymmetrical biaryls, which have a crucial role in natural products and pharmaceutical compounds [1]. Recently the heterogenisation of homogeneous catalysts and their investigation in synthesis of fine chemical has become a major area of research. 1,2- Bidentate carboxyl groups can form an efficient and stable chelates with transition metals [2]. Therefore, herein we wish to synthesis a heterogeneous Palladium catalyst coordinated to dicarboxylic acid ligand supported on SBA-15 and demonstrate its catalytic activity in Suzuki-Miyaura reactions.
