Photolysis of hexacarbonylmetal(0) complexes of the Group 6 elements in the presence of vinylferrocene in an n-hexane solution at −15 °C yields pentacarbonyl (η2-vinylferrocene)metal(0) complexes as the sole photo-substitution product, different from the general reaction pattern observed for the same Group 6 metal carbonyls with other olefins. M(CO)5(η2-vinylferrocene) complexes (M=Cr, Mo, W) could be isolated from the solution and characterized by using spectroscopic techniques. The complexes were found to be not very stable and their stability increases in the order Cr
