Tricarbonyl(η6-1-methylindole)chromium(0) is lithiated by n-butyl-lithium at C-2 whereas tricarbonyl-(η6-1-methyl-2-trimethylsilylindole)chromium(0) is lithiated predominantly at C-7, as shown by X-ray analysis of the derived 7-ethoxycarbonyl derivative, and the 7-lithio species is substituted in good yield by a range of electrophiles.
