Abstract

Abstract: The reaction of complex [ μ -SCH(CH3 )CH(CH3 )S- μ ]Fe2 (CO)6 (1 ) with trans -1, 2-bis(diphenylphosphino)ethylene ( trans -dppv) in the presence of Me3 NO∙2H2 O in CH2 Cl2 /CH3 CN afforded complex {[ μ -SCH(CH3 )CH(CH3 )S- μ ]Fe2 (CO)5 }2 ( trans -dppv) (2 ) with a bridging dppv. Complex [ μ -SCH(CH3 )CH(CH3 )S- μ ]Fe2 (CO)4 ( cis -dppv) (3 ) was prepared by the reaction of1 with cis -dppv and Me3 NO∙2H2 O. The new complexes2 and3 were characterized by elemental analysis, spectroscopy, and X-ray diffraction analysis. Abstract :
