The reaction of Au(CO)Cl with 1,3‐di‐ tert ‐butylimidazol‐2‐ylidene and 1,3‐dimesitylimidazol‐2‐ylidene in toluene at room temperature results in CO evolution and readily affords in high yield the adducts 1a and 1b , respectively. The reaction of 1a and 1b with ethynylmagnesium chloride in THF yields 2a and 2b , respectively. The crystal structures of 1a , 1b , and 2a were determined. (© Wiley‐VCH Verlag GmbH & Co.
