摘要：

The potassium salts of eta-6-indenyl-, eta-6-(1-phenyl)indenyl-, and eta-6-(1,3-diphenyl)indenyl-Cr(CO)3 anions have been prepared in THF solution at -30-degrees-C and fully characterized by H-1 NMR spectroscopy. At higher temperatures, the Cr(CO)3 group migrates from the benzo- to the cylopentadienyl-ring, the migration being slowest for the 1,3-diphenyl-substituted species. A kinetic study indicates that an intra-molecular pathway through an eta-3 intermediate is preferred.
