Abstract
Silanides ([R3Si–]) and germanides ([R3Ge–]) are attracting attention as donor ligands for transition metals, but their use as supporting ligands in catalysis is limited, often due to their high reactivity. In this study, we report the preparation and characterization of gold(I) complexes bearing the anionic silanide and germanide ligands tmimSi– and tmimGe– (tmimH3 = tris(3-methylindol-2-yl)methane), which are stabilized by a bicyclic cage structure. Both the silanide and germanide complexes catalyze the hydroamination of 1-ethynyl-4-fluorobenzene with aniline. The germanide complexes are more efficient than their silanide analogues, likely due to their more electrophilic character. These results show that both ligand types can be used as supporting ligands in catalysis, which warrants further investigations.
期刊介绍:
Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
