General description

A robust palladium heterogenous catalyst.

Application

Catalyst for:
  • Solvent-free hydrogenation
  • Aerobic alcohol oxidation
A recyclable nanocatalyst for the racemization of primary amines. When used in conjunction with a lipase produces enantiopure amines by Dynamic Kinetic Resolution.
