报告摘要

It is important to develop metalloprotein-inspired polymer-supported metal catalysts, ensuring catalytic activity, stability and reusability for safe, non-toxic, sustainable chemistry, and green organic synthesis. We have reported convoluted polymeric metal catalysts for organic transformation reactions, where a soluble linear polymer having multiple ligand groups is cross-linked with transition metals via coordinative complexation. Here, we report development of a highly active and reusable polymeric imidazole palladium catalyst MPPI-Pd. By using 0.28 mol ppm (0.000028 mol %) to 0.1 mol % of MPPI-Pd, the allylic arylation, the Suzuki-Miyaura reaction, and the Mizoroki-Heck reaction proceeded smoothly to give the corresponding coupling products in high yield. MPPI-Pd was reused without loss of catalytic activity.[1] This methodology was also applied to preparation of highly active copper catalysts[2] and others.[3,4]
