Effect on orthometallation of NHC palladium complexes toward the catalytic activity studies in Suzuki coupling reaction

Abstract

Herein, we report an approach to improve catalytic activity for cross-coupling reactions. N-Heterocyclic carbene (NHC) palladium complexes bearing a nitrogen-based ligand without orthometallation complexes show remarkable activities in Suzuki coupling reaction than orthometallation. Aryl chlorides examples employed in air and ambient temperature in Suzuki coupling reaction to reach completion within few minutes.
