Features and Benefits

The advantages of using Pd EnCat^® catalysts are:

low residual metal levels in crude product
easy recovery of catalyst
compatibility of immobilized metal with various ligands to effect C–C bond forming reactions
safer and easier to handle than Pd/C for hydrogenation
efficiency and economy gains through recovery and recycling

General description

It is an encapsulated catalyst (EnCat^®), wherein palladium acetate and tri-o-tolylphosphine (TOTP) are microencapsulated within a polyurea matrix, which prevents palladium leaching.

Polyurea-encapsulated palladium(II) acetate: a robust and recyclable catalyst for use in conventional and supercritical media.

Steven V Ley et al.

Chemical communications (Cambridge, England), (10), 1134-1135 (2002-07-19)

Palladium(II) acetate microencapsulated in polyurea (MC-[Pd]) is an economical and versatile heterogeneous catalyst for a range of phosphine-free cross-coupling reactions in both conventional solvents and supercritical carbon dioxide (scCO2); the catalyst can be recovered by a simple filtration and recycled
