Lithiation of tricarbonyl-η6-(1-tri-isopropyisilylindote) chromium (0) and η6-(1-tri- isopropylsilyl-3-methoxymethylindole) tricarbonylchromium (0) followed by an electrophilic quench produced a series of 4-substituted indole complexes. For the 4-acyl,-allyl and- alkenyl analogues, transmetallation of the lithio-species to the corresponding cupro- complexes and reaction with the appropriate halides (in the alkenyl case with palladium ...
