Recent developments in transition metals supported on functionalized materials for enhancing Suzuki reactions

The construction of aryl˗aryl, aryl˗heteroaryl or heteroaryl˗heteroaryl linkages via Suzuki coupling reactions is essential and common in industrial applications, which warrants the development of the pharmaceutical drugs, dyes, and agrochemicals fields. In this review, the general mechanism and practical application of Suzuki reactions are briefly described. Importantly, special attention is paid to the C-C coupling activity of supported Pd catalysts based on diverse recently developed materials. Furthermore, the application of the transition metals-based heterogeneous catalysts (Ni, Cu, Fe, Co) in Suzuki reactions was also summarized and compared. It is anticipated that this overview will improve current understanding and motivate further innovation toward the development of highly efficient and low-cost heterogeneous catalysts for Suzuki coupling reactions.
