have been examined. In such model complexes, the Tp− simulates the coordination environment provided by three imidazole ligands in proteins. In organometallic chemistry, Tp*Rh(CO)2 and related complexes participate in C-H activation reactions. Derivatives of Grignard reagents can be generated, such as TpiBuMgCH3.
