Abstract Classical methods for the synthesis of indan-1, 3-dione derivatives failed when applied to their tricarbonylchromium complexes. The desired 2-substituted (η 6-indan-1, 3- dione) tricarbonylchromium complexes were prepared starting from protected indan-1, 3- dione derivatives such as bis (dioxolanes) and enol ethers. Tricarbonylchromium complexes of indan-1, 3-dione having at least one hydrogen at C-2 are unstable. Nevertheless, ...
