Palladium-catalyzed C-C and C-N bond-forming reactions are among the most versatile and powerful synthetic methods. For the last 15 years, N-heterocyclic carbenes (NHCs) have enjoyed increasing popularity as ligands in Pd-mediated cross-coupling and related transformations because of their superior performance

Pd-N-heterocyclic carbene (NHC)-catalyzed Buchwald-Hartwig amination protocols mediated by Pd-PEPPSI precatalysts is described. These protocols provide access to a range of hindered and functionalized drug-like aryl amines in high yield with both electron-deficient and electron-rich aryl- and heteroaryl chlorides and bromides.

PEPPSI™ Catalyst - Introduction, advantages and applications

PEPPSI™-IPent for Demanding Cross-Coupling Reactions

Professor Mike Organ and co-workers have developed the PEPPSI™ (Pyridine-Enhanced Precatalyst Preparation Stabilization and Initiation) precatalysts for palladium-catalyzed cross-coupling reactions.

PEPPSI™ Catalysts

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.
