Details

SiliaCat Pt0 is made of organosilica physically doped with nanostructured Platinum(0), and is both stable and efficient.
This catalyst was successfully prepared by a novel and simple sol-gel route.
In the new procedure, Pt nanoparticles (uniformly in the range 1.7–3.15 nm) are encapsulated via an alcohol-free sol-gel process typical of enzyme sol-gel encapsulation.

 

Typical Applications: Selective reduction of nitroarenes, Hydrosilylation

Details

The significant costs associated with precious metal catalysts and their undesired tendency to remain in organic products has generated interest for an increase in reactivity and ways to recover and reuse these metals. SiliaCat® DPP-Pd is a unique diphenylphosphine palladium (II) heterogeneous catalysts made from a leach-resistant organoceramic matrix.

SiliaCat DPP-Pd features include:

  •  Ease of handling (no static charge) and purification
  •  Accurate Loading
  •  High Reactivity
  •  Can be used in microwaves reactors
  •  Suitable for continuous process catalysis (FLOW)
  •  No swelling, solvent independency, mechanical and thermal stability
  •  Leach-resistant & reusable
  •  Air stable, inert conditions not needed
  •  Scalable

SiliaCat DPP-Pd is an effective and useful palladium catalyst (but not limited to) for couping reactions such as Suzuki, Heck, Sonogashira, Kumada, Stille, Negishi, and Borylation.
