Support group: Coordinated to the tricarbonylchromium fragment, a typically unstable benzylic organolithium can participate directly in cross-coupling reactions with aryl bromides to form polyarylated methane derivatives (see scheme). Cr(CO)3 assistance leads to reactivity with a variety of coordinated substrates and-given multiple benzylic sites-can effect up to six coupling events per arene. Chemical equation presented
INDENYL AND FLUORORENYL TRANSITION METAL COMPLEXES X. ANIONIC CHROMIUM TRICARBONYL COMPLEXES OF FLUORADENE, SUBSTITUTED FLUORENES AND INDENE: THE STRUCTURE OF ION PAIRS AND η6->η5 REARRANGEMENTS

The metallotropic η6 η5 tautomeric equilibrium in anionic chromium tricarbonyl complexes of fluoradene, substituted fluorenes and indene has been studied.A criterion is proposed for determining the ion-pair type in η6-anions according to the E-band splitting in the ν(CO) region of their IR spectra.The influence of ligand structure and cation solavtion on Keq. is discussed.
