Lithiation of chloro- and methoxy-(η6-benzene)tricarbonylchromiumcomplexes yielded, after electrophilic quench with a Weinreb amide, the corresponding benzoyl-substituted complexes. One of them has been investigated by an X-ray diffraction study.

Regioselectively lithiated tricarbonyl-η6- arenechromium(0) complexes can be acylated and allylated in high yield via the analogous arylcopper dimethyl sulphide complexes, and vinylated and arylated via palladiumcatalysed cross coupling of the arylcopper dimethyl sulphide complexes with vinyl and aryl halides.
