The oxidation of the carbon-centered [(η6-C13H9)Cr(CO)3]− anion (1−) results in formation of (μ-η6:η6-9,9′-bifluorenyl)bis-chromiumtricarbonyl (3) due to coupling of the intermediate carbon-centered radical (1.). The oxidation of the metal-centered anion [(η5-C13H9)Cr(CO)3]− (2−), which is isomeric to the 1− anion, gives an equilibrium mixture of the chromium-centered radical {(η5-C13H9)Cr(CO)3}. (2.) and its dimer [(η5-C13H9)Cr(CO)3]2 (6). Radical2. readily reacts with MeI and the solvent (THF); the resulting derivatives, (η5-C13H9)Cr(CO)3R (R=Me (10); R=H (7)), undergo fast ricochet inter-ring η5→η6 rearrangements into (η6-9R-C13H9)Cr(CO)3 (R=CH3 (9); R=H (4)). |
