CNC pincer palladium complex supported on magnetic chitosan as highly efficient and recyclable nanocatalyst in C ─C coupling reactions

A stable magnetic chitosan ‐supported triazine‐bridged bisimidazolium pincer palladium complex was synthesized as a highly active catalyst for cross‐coupling reactions. A stable and durable magnetic chitosan ‐supported triazine‐bridged bisimidazolium pincer palladium catalyst (Fe3O4@ChC@CNC ‐PdII) was synthesized and characterized using various techniques. The Fe3O4@ChC@CNC ‐PdII complex displayed high activity in the production of substituted biaryls via the cross ‐coupling reactions of aryl halides with arylboronic acids. Also, this catalyst could be simply recovered from the reaction mixture and reused in 13 consecutive runs with no loss of its catalytic activity.
