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