  isophthalaldimine ligand in the rhodium(III) dihalide compounds [RhX2(NCN)] coordinate quite strongly, since the addition of an excess of pyridine or PPh3 resulted in their coordination to rhodium, not in substitution of the imine moieties. Transmetalation of the rhodium(III) isophthalaldimine dihalide compounds [RhX2(NCN)] with Me2Zn provides novel rhodium(III) methyl halide isophthalaldimine compounds

  transition metal carbonyls. Thus, the reaction of 1–3 with [M(CO)5THF] (where M = Cr, W) or [Mo(CO)5(Me3N)] gave complexes [(ArE)M(CO)5] [where E = As and M = Cr (1a), Mo (1b), W (1c); E = Sb and M = Cr (2a), Mo (2b), W (2c); E = Bi and M = Cr (3a), Mo (3b), W (3c)]. Analogously, the treatment of 1–3 with [Fe2(CO)9] resulted in the formation of the complexes [(ArE)Fe(CO)4] [where E = As (1d), Sb (2d) or Bi (3d)]

  [CNtBuTeCl2]OTf and [NCNtBuTeCl2]OTf were shown to undergo a controlled hydrolysis to the corresponding telluroxanes. All compounds were studied by multinuclear NMR spectroscopy in solution and for selected compounds solid state 125Te NMR spectroscopy and single-crystal X-ray diffraction analysis were performed. The Lewis acidity of the studied cations was examined by the Gutmann–Beckett method using Et3PO as the

  The synthesis of a germylidenide anion by the CC bond activation of a bis(germylene) is described. The reaction of the 2,6-bis(imino)phenyl bromide 1 with nBuLi, followed by reacting with GeCl2 center dot dioxane, afforded the chlorogermylene [LGeCl] (2, L = 2,6-(HCNtBu)(2)C6H3). It was then reacted with 1 equiv of lithium in tetrahydrofuran (THF), which proceeded through the reduction of the imine skeleton, along with the CC bond formation, to afford the bis(germylene) [2-(HC-NtBu)-6-(HC=NtBu)C6H3Ge:](2) (3). It was further reacted with 2 equiv of lithium in THF, which proceeded through the reduction of the germanium(II) centers, followed by the homolytic cleavage of the CC bond, to form the lithium germylidenide [LGeLi](2) (4). Compounds 2-4 were characterized by NMR spectroscopy and X-ray crystallography. Their bonding natures were also investigated by theoretical studies.

  The synthesis and characterization of the stannylidenide anion [LSn:](-) (L = 2,6-(CH=NBut)(2)C6H3) supported by the 2,6-diiminophenyl ligand is described. The reaction of the chlorostannylene [LSnCl] (2) with excess KC8 in diethyl ether at room temperature afforded the distannylene [LSn:](2) (3). The treatment of 3 with 2 equiv of KC8 in tetrahydrofuran (THF) resulted in the cleavage of the Sn-I-Sn-I bond in 3 to afford the potassium stannylidenide [LSnK.THF] (4). The molecular structure of compound 4 as determined by single-crystal X-ray diffraction analysis shows that the K atom is eta(5)-coordinated to the low-valent tin heterocycle. Moreover, the negative charge at the Sn atom in compound 4 is stabilized by an electron delocalization in the low-valent tin heterocycle.
