Recent Progress on the Application of the Polyaniline-Pd Catalysts for C-C Cross-coupling Bond Forming Reactions: Trend and Future Analysis

Abstract

In this review recent progress on the application of the polyaniline supported palladium catalysts in different organic transformations focusing on different C-C bond forming reactions such as Suzuki coupling, Heck reactions, oxidative Heck coupling, Ullmann coupling, Sonogashira and related chemistry. Effect of catalyst preparation, characteristic of the support and supported palladium species on the outcome of the catalyst efficiency are also highlighted. Finally, the emerging trend is summarized for the future of this unique modular catalytic system.
