Reaction of ruthenium phenyl acetylide with iron-chalcogen clusters and iron pentacarbonyl

Photolysis of a THF solution containing ruthenium acetylide [(η5-C5H5)Ru(PPh3)2(η1-CCPh)] with [Fe3(CO)9(μ3-Se)2] cluster affords an adduct [{μ-SeC(CpRu(PPh3)(CO))C(Ph)Se}(CO)6Fe2] (1), while under similar reaction condition with [Fe3(CO)9(μ3-Te)2] cluster a Ru-inserted product [(η5-C5H5)(PPh3)(η1-CCPh)RuFe2(μ3-Te)2(CO)6] (2) was obtained. Under thermal condition [(η5-C5H5)Ru(PPh3)2(η1-CCPh)] react with Fe(CO)5 to give an acetylide stabilised Fe2Ru mixed metal cluster [(η5-C5H5)RuFe2(CO)7(η2:η2:η1-CCPh)], (3).
