Highly effective photoativation Pd catalyst for Suzuki coupling reaction

Suzuki coupling reaction is widely applied for constructing biaryl skeletons in various fields. Designing and developing highly effective catalysts are essential regarding the Suzuki coupling reaction. Here, we report a simple light irradiation approach to achieve the highly efficient Suzuki coupling reaction via the application of low valence Pd homogeneous catalyst. The catalyst exhibited a TOF value of 76,000 h−1. We systematically investigated the impact of various experimental conditions on catalytic performance and further clarify the evolution of Pd species during the light irradiation and catalytic reaction process. This work provides a facile strategy for designing highly effective catalysts for the Suzuki coupling reaction and understanding the detailed evolution process of Pd during the reaction process.
