摘要

Development of two transition metal based catalytic systems offer advantages over single metal based catalytic systems. More interestingly heterogenous two transition metal based catalytic systems offer easy separation, reusability and high thermal stability. Here, we report a systematic approach to develop heterogenous two transition metals namely palladium and ruthenium-based catalyst for the tandem Suzuki coupling and transfer hydrogenation reaction. The catalysts were characterized using a wide variety of techniques including SEM, TEM, solid state NMR and ICP-OES. The catalytic system showed good reactivity towards tandem Suzuki coupling and transfer hydrogenation reaction, wide substrate scope and very good reusability.

Graphical Abstract

Cross-linked polystyrene anchored palladium and ruthenium based heterogenous system was developed for one-pot reaction namely Suzuki coupling and transfer hydrogenation reaction. The stability and recyclability of the catalyst for the Suzuki coupling and transfer hydrogenation reaction was also studied for up to 5 cycles.
