Influence of Carbene and Phosphine Ligands on the Catalytic Activity of Gold Complexes in the Hydroamination and Hydrohydrazination of Alkynes

Journal Article · · ACS Catalysis

Through kinetic measurements, catalytic and stoichiometric experiments, and DFT calculations, we compare the catalytic activity of gold complexes supported by a variety of ligands (R3P, NHC, CAAC-5, CAAC-6, and BiCAAC) in the hydroamination and hydrohydrazination of alkynes. This study provides a rationale for the superior efficiency of a gold complex bearing a bicyclic (alkyl)(amino) carbene (BiCAAC). We demonstrate that this ligand motif, which is readily available, provides a durable gold catalyst that is able to compete with sophisticated state-of-the-art phosphine and NHC ligands, which feature secondary interaction capabilities.
