Photolysis of a benzene solution containing Fe(CO)5 and [(η5-C5R5)Mo(CO)3(C≡CPh)] yielded mixed-metal clusters [(η5-C5R 5)Fe2Mo(CO)8(μ3- η1:η2:η2-CCPh)] (R = H, 1; Me, 2) and [(η5-C5H5)Fe3Mo(CO) 11(μ4-η1:η1: η2:η1-CCPh)] (3). When a mixture of [(η5-C5Me5)Mo(CO)3(C≡CPh)] , Fe(CO)5, and phenylacetylene was photolyzed, coupling of the acetylide and acetylene was observed and the mixed-metal cluster [(η5-C5Me5)Fe2Mo(CO) 7(μ3-η1:η4: η2-C(H)C(Ph)C(Ph)C)] (4) was obtained. Interestingly, use of a bulky substituent on the free acetylene in the reaction mixture did not produce analogues of 4. Reaction of Fe(CO)5 with ferrocenylacetylene produced three different compounds, tetracarbonyl(2-ferrocenylmaleoyl)iron (5), 2,5-diferrocenylquinone (6), and 2,6-diferrocenylquinone (7). All new compounds were characterized by IR and 1H and 13C NMR spectroscopy. Structures of 2-7 were established crystallographically.
