  In Search of Cationic Germanium(II)−Transition Metal Complexes L²Ge⁺W(CO)₅ and L²Ge⁺W(CO)₄Ge⁺L²

  摘要：

  New germanium(II) -tungsten complexes [L-2(X)Ge](n)W(CO)(6-n) (L-2 = NPhC(Me)CHC(Me)-NPh, n = 1, X = OTf (2); n = 2, X = Cl (13)) have been synthesized and characterized by X-ray crystallography. In compound 2 the triflate was found to be very weakly coordinating to the germanium in the solid state, and this result is confirmed by DFT calculations. All the spectroscopic data are consistent with the L-2(X)Ge ligands being good sigma-donors and poor pi-acceptors in these complexes, similar to the phosphine ligands in homologous R3P complexes. Starting from the chlorogermanium(II)-tungsten complexes (L2(Cl)Ge)nW(CO)6-n (n = 1 (1), n = 2 (13)), metathesis reactions with halide or weakly coordinating anions A(-)(A- = TfO-, BPh4-, PF6-) have been investigated as a general approach to obtain the cationic germanium species [(LGe+)-Ge-2](n)W(CO)(6-n). In the case of A(-) = TfO-, spontaneous dissociation of the anion leading to an equilibrium between a neutral and a cationic tetracoordinated germanium species is observed in coordinating solvents. Treatment of L-2(X)Ge with MX3 (M = Ga, X = Cl; M = In, X = I) afforded the neutral complexes (LMX2)-M-2 (M = Ga (7) and In (8)) by ligand transfer reactions. The crystal structure of 8 was determined by X-ray structure analysis.

  crystal structures of 1−3 and their electronic structures have been determined by X-ray diffraction and UV-photoelectron spectroscopy (UPS), respectively. DFT calculations on 1 and 3 were carried out at the B3LYP level of theory. Natural bond orbital analysis for the model molecules 1‘ and 3‘ (without phenyl) gives information on the Ge−Σ bonding. It turns out from the NMR, mass spectroscopy, and X-ray

  Reactions of the stable heteroleptic halodivalent species L-2(X)M [L-2 = PhNC(Me)CHC(Me)NPh; M = Ge, X = C1 (1) X = 1 (2); M = Sn, X = Cl (5)] with the intermediate metal complexes W(CO)(5) THF and Fe(CO)(4) have provided the new halogermylene- or stannylenetungsten- and iron-complexes L-2(X)MM'L-n' [M'L-n' = W(CO)(5), M = Ge, X = Cl (3), X = 1 (4); M'L-n' = Fe(CO)(4), X = Cl, M = Ge (6), M = Sn (7)] respectively, complexes 3, 4 and 6, 7 have been characterized via X-ray crystallography and a detailed discussion of their structures is presented. All the MM' bonds are very short but calculations are consistent with the (LMX)-M-2 ligands being good sigma-donors and very poor pi-acceptors in complexes 3, 4 and 6, 7. Selective metathesis reaction between 3 and MeLi resulted in the formation of the stable monomeric complex L-2(Me)GeW(CO)(5) (8). (C) 2003 Elsevier Science B.V. All rights reserved.

  The first monomeric germanethiocarbamyl halides containing a chelating beta-diiminate ligand, L-2(CI)Ge=Y (L-2 = PhNC(Me)CHC(Me)NPh; Y = S (2), Y = Se (3)), have been prepared by the reaction of the corresponding heteroleptic halogermylene L-2(Cl)Ge (1) with elemental sulfur or black selenium in refluxing toluene. Single-crystal X-ray structural analyses of 2 and 3 reveal that the germanium centers reside in highly distorted tetrahedral environments in these compounds; short Ge-Y distances (Ge-S = 2.07 Angstrom (2); Ge-Se = 2.21 Angstrom (3)) are indicative of an unsaturated character of these germanium-chalcogen bonds. Selective reactions between 2 or 3 and MeLi afforded the corresponding alkylated germanechalcogenones L-2(Me)Ge=Y (Y = S (4), Se (5)).
