was isolated from a reaction between Na2PdCl4 and MeOOCCH2CH2SeNa. All these complexes have been characterized by elemental analysis, IR, UV–Vis and NMR (1H, 13C, 31P, 77Se, 195Pt) spectroscopy. Structures of trans-[Pd2Cl2(μ-SeCH2CH2COOMe)2(PPh3)2] (2d), [Pt2Cl2(μ-Cl)(μ-SeCH2CH2COOMe)(PnPr3)2] (3e), [Pd3Cl2(μ-SeCH2CH2COOMe)4(PnPr3)2] (5) and [Pd(SeCH2CH2COOMe)2]6 (6) have been established unambiguously
通过在甲醇中酯化(HOOCCH 2 CH 2 Se)2制备了二硒化物(MeOOCCH 2 CH 2 Se)2(1)。NaBH 4在甲醇中对Se-Se键在1中的还原性裂解生成MeOOCCH 2 CH 2 SeNa。在与[M不同的化学计量反应的后者2氯2(μ-Cl)的2(PR 3)2 ],得到了各种组合物的产品[M 2氯2(μ-SECH 2 CH 2COOMe)2(PR 3)2 ](2);[M 2氯2(μ-Cl)的(μ-SECH 2 CH 2 COOMe)(PR 3)2 ](3); [钯2(SECH 2 CH 2 COOMe)2(μ-SECH 2 CH 2 COOMe)2(PR 3)2 ](4); [钯3氯2(μ-SECH 2 CH 2 COOMe)4(PR 3)2 ](5)。复合物的治疗2与[M 2氯2(μ-Cl)的2(PR 3)2 ],得到的复合物3中几乎定量的产率。这些反应中各种产物的形
