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.

(Fluoroarene)tricarbonylchromium(0) complexes were found to undergo Suzuki and Stille cross-coupling reactions to form functionalised biaryl and styrene complexes in up to 87 and 52% yields, respectively. The Suzuki reactions were optimal with dipalladium tris(dibenzylideneacetone)–trimethylphosphine–caesium carbonate in DME at reflux. The Stille reactions were optimal with dipalladium tris(dibenzylideneacetone)–trimethylphosphine–caesium fluoride in DME at reflux and neither was adversely affected by a methoxy group on the complexed ring. The Suzuki reaction tolerated a chloro group on the arylboronic acid ring but not a bromo group.
