Professor Mike Organ, along with Drs. Chris O’Brien and Eric Kantchev, have developed an elegant Pd-NHC catalyst system. The title complex PEPPSI™ stands for Pyridine-Enhanced Precatalyst Preparation Stabilization and Initiation.
PEPPSI™ Catalysts are novel state-of-the-art catalyst that successfully performs cross-coupling niche reactions.
Professor Mike Organ at York University, along with co-workers Dr. Chris O’Brien and Dr. Eric Kantchev, have developed an palladium N-heterocyclic-carbene (NHC) catalyst system. They reacted PdCl2with a bulky NHC ligand, 2,6-diisopropylphenyllimidazolium chloride (IPr), and an α-donating 3-chloropyridine ligand for stability. The title complex, PEPPSI™, stands for Pyridine-Enhanced Precatalyst Preparation Stabilization and Initiation. Sigma-Aldrich offesr gram-scale quantities of the PEPPSI™ catalyst in collaboration with the Organ research group.
