| Abstract: | UV irradiation of the diphenylchalcogenides Ph2Se2 or Ph2Te2 in the presence of (η5-MeCp)Mo(CO)3]2 induces rapid reaction to give the double μ-EPh bridged compounds (η5-MeCp)Mo(CO)2(μ-EPh)]2. Subsequent decarbonylation by mild thermolysis in vacuo gives (η5-MeCp)Mo(CO)(μ-SePh)]2 or (η5-MeCp)Mo(CO)(μ-TePh)2 in good yields. The new compounds were characterized by elemental analysis, infrared and mass spectra. The mixed Se/ Te bridged complex (η5-MeCp)Mo2(Co)4(μ-SePh)(μ-TePh)] was not obtained by UV irradiation of (η5-MeCp)Mo(CO)3]2 in the presence of a mixture of Ph2Se2 and Ph2Te2. |
