Synthesis and characterization of cyclopentadienyltricarbonyl tungsten selenocarboxylate and selenosulfonate complexes

摘要

Cyclopentadienyltricarbonyl tungsten selenocarboxylate complexes CPW(CO)(3)SeCOR (1) (R = C6H5 (a), 3,5-C6H3(NO2)(2) (b), 3-C6H4NO2 (c), 4-C6H4NO2 (d), CH3 (e)) and cyclopentadienyltricarbonyl tungsten selenosulfonate complexes CpW(CO)(3)SeSO2R (2) (R = C6H5 (a), 4-C6H4CH3 (b), 4-C6H4OCH3 (C), 4-C6H4Cl (d), CH3 (e)) have been prepared from the tungsten anion [CPW(CO)(3)Se](-) and acid- or sulfonyl chlorides respectively. The new complexes (1 and 2) have been characterized by IR, H-1 NMR spectroscopies as well as elemental analysis. The crystal structure of CPW(CO)(3)SeCO-3-C6H4NO2 (1c) was determined.
