Organometallic Complex Synthesis and Catalysis

Bigger and better! The single-component zwitterionic gold catalyst formed by the coordination of a phosphine ligand bearing an inert and noncoordinating carborane substituent, CB11Cl11−, to an AuI ion exhibited the highest reported activity for the hydroamination of alkynes with amines (see scheme). The highest turnover number observed for hydroamination with this catalyst exceeded a stunning 95 000.
