    result in a high coordinated homoleptic complex but instead yields [(coe)(toluene)RhGa(DDP)}(CF3SO3)] (4). The common feature of 2 and 4 in the solid state structure is the presence of short CF3SO2O···Ga contacts involving the GaCp* or rather the Ga(DDP) ligand. Compounds 1, 2, and 4 have been fully characterized by single crystal X-ray diffraction, variable temperature 1H and 13C NMR spectroscopy, IR

    A series of heteroleptic complexes [Ni(PEt3)4–n(ECp*)n] (E = Al, Ga, Cp* = pentamethylcyclopentadienyl, n = 0–4) was prepared and characterized by experimental as well as computational means. The series of compounds was studied with respect to ligand dissociation processes which are fundamental for reactivity. In contrast to the homoleptic complexes [Ni(PR3)n] phosphine dissociation is remarkably suppressed

    present the first cyclic five-membered triel(I) carbenoides E(AmIm) for E = Ga, In, Tl; AmIm = amido imidazoline-2-imine, which fill the current gap between four- and six-membered triel(I) carbenoides supported by HGiso and HNacNac. Ga(AmIm) can act as a strong σ-donor ligand in transition metal complexes, while the intermediacy of the Al(I) carbenoide Al(AmIm) is rationalised based on the isolation
    我们提出了第一个环状的五元triel(I)碳烯化物E(AmIm),其中E = Ga,In,Tl;AmIm =酰胺基咪唑啉-2-亚胺,它填补了由HGiso和HNacNac所支持的四元和六元triel(I)碳烯化物之间的当前缺口。在过渡金属配合物中,Ga(AmIm)可以充当强大的σ供体配体,而Al(I)碳烯化物Al(AmIm)的中间体是基于Al(III)插入产物的分离而合理化的。
  • Salt metathesis as an alternative approach to access aluminium(<scp>i</scp>) and gallium(<scp>i</scp>) β-diketiminates

    the respective aluminium(i) and gallium(i) β-diketiminates I and II. The protocol gives better yields compared to the established procedures and avoids the use of strong reducing agents such as metallic potassium. Furthermore, the aluminium(i) β-diketiminate I was found to react with itself and yields upon C-N bond cleavage and hydrogen-atom transfer the asymmetric dinuclear aluminium(iii) complex V
    盐复分解,即β-二酮化钠分别与(AlCp *)4和GaCp *的反应,是获取各自的β-二酮化铝I和II的有价值的途径。与已建立的程序相比,该方案可提供更好的收率,并且避免使用强还原剂,例如金属钾。此外,发现β-二酮铝(i)与自身发生反应,并在CN键断裂和氢原子转移时产生不对称的双核铝(iii)配合物V,其易于通过结晶与I分离。通过DFT和DLPNO-CCSD(T)计算对反应机理进行了探索,计算结果与实验结果吻合良好。
