N2 - A carbonyl ligand of π-arenetricarbonylchromiun(0) complexes is photochemically displaced to give π-arenedicarbonyl complexes of chromium(0) with thio-ether ligands. In contrast, irradiation of π-arenetricarbonylchromium compounds with dithio-ester and trithiocarbonate ligands yields only pentacarbonyl complexes. Substitution of the π-arene ring, the thio-ether ligand, or both, is easily achieved at room temperature and in polar solvents. The crystal structure of cis-tetracarbonyl(methyl-1,3-dithian-2-methyl-2-dithiocarboxylate)chromium(0) shows remarkably similar CrS bond distances of 2.379(2) and 2.383(2) Å for the respective thio-ether and dithio-ester sulphur-donor atoms of the bidentate ligand.
