Rapid “Mix‐and‐Stir” Preparation of Well‐Defined Palladium on Carbon Catalysts for Efficient Practical Use

Abstract: A facile direct deposition approach for the preparation of recyclable Pd/C catalysts simply by stirring a solution of tris(dibenzylideneacetone)dipalladium(0) with a suitable carbon material was evaluated. An extraordinarily rapid catalyst preparation procedure (<5 min) under mild conditions and its excellent performance in cross‐coupling and hydrogenation reactions were demonstrated. The key point for catalyst design is the direct deposition of Pd0 centers onto the highly accessible surface area and the avoid… Show more

“…Enough is to cite here the new Pd/C catalyst made in situ in less than 5 minute via direct deposition of Pd 0 nanoparticles onto the highly accessible surface area and the avoidance of ill-defined Pd II /Pd 0 states. [33] Today, catalysis companies supply the fine chemical and pharmaceutical industries mainly with catalysts used to accomplish conventional hydrogenation, asymmetric hydrogenation, cross coupling and ring closing metathesis reactions. Underlining the societal relevance of catalysis, all the aforementioned processes were recognized with the Nobel prize: Sabatier (along with Grignard) in 1912 for his studies on the direct hydrogenation of organic molecules on powdered nickel; [34] Knowles (alongside Noyori and Sharpless) in 2001 for the discovery that rhodium coordinated by chiral phosphine ligands performs asymmetric catalytic hydrogenation; [35] Schrock for catalytic metathesis reactions in 2005; [36] Suzuki, Heck, and Negishi in 2010 for palladium-mediated cross-coupling reactions.…”
