Abstract

(Figure Presented) Catalyst tuning by changing ligands is a well-established protocol in transition-metal chemistry. N-Heterocyclic carbenes (NHCs) and tertiary phosphines (R<inf>3</inf>P) are the ubiquitous ligand actors. Here we demonstrate that the relative σ-donor/π-acceptor ability of the NHC ligand itself can be influenced by a simple substituent-controlled conformational change, thereby directly impacting the reactivity of the transition-metal complex.
