摘要
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 la and 1b, respectively. The reaction of 1a and 1b with ethynylmagnesium chloride in THF yields 2a and 2b, respectively. The crystal structures of la, 1b, and 2a were determined.
