isolation of the first nickel(III) complexes containing thio- or seleno-ether donor groups is reported, specifically [Nio-C6H4(PPh2)(EMe)}Br3] (E = S, Se), [Nio-C6H4(PMe2)(SeMe)}2Br2]BF4, and [Nio-C6H4(AsMe2)(SeMe)}2Br2]BF4. Palladium(IV) and platinum(IV) complexes of o-C6H4(AsMe2)(EMe) of type [Pd(LL)X4] or [Pt(LL)X4] (X = Cl or Br) are also described. The complexes have been characterised by analysis
据报道,第一批含硫醚或硒醚供体基团的镍(III)配合物的分离,特别是[Ni o -C 6 H 4(PPh 2)(EMe)} Br 3 ](E = S,Se) ,[Ni o -C 6 H 4(PMe 2)(SeMe)} 2 Br 2 ] BF 4和[Ni o -C 6 H 4(AsMe 2)(SeMe)} 2 Br 2 ] BF 4。o -C 6 H 4的钯(IV)和铂(IV)配合物还描述了类型为[Pd(LL)X 4 ]或[Pt(LL)X 4 ](X = Cl或Br)的(AsMe 2)(EMe)。适当地通过分析,IR,UV-Vis,多核NMR和ESR光谱对复合物进行了表征。在所有情况下,杂化基团VB-VIB供体配体在稳定高氧化态金属中心方面均不如二膦或二ar胺有效。
