Tricarbonyl(η6-indole)chromium(0) complexes substituted at the C2 and/or C3 positions have been reduced to the corresponding indoline complexes by the action of a hydride donor in trifluoroacetic acid. NaBH3CN and NaBH4 were found to be superior to Et3SiH as hydride sources. In general, reductions involving the use of NaBH3CN were found to occur with greater stereoselectivity as compared to reductions

Tricarbonyl-(η6-1-tri-isopropylsilylindole)chromium (0), lithiated selectively at C-4 by n-butyl-lithium–N,N,N′,N′-tetramethylethylenediamine (TMEDA), can be substituted in good yield by a range of electrophiles; the method has been used to synthesise 4-prenylindole.
