  Synthesis and Structural Characterization of 1-Mesityl-1,3-dihydro-imidazole-2-selone and Bis(1-mesitylimidazol-2-yl)diselenide:  Experimental Evidence That the Selone Is More Stable Than the Selenol Tautomer

  摘要：

  1-Mesityl-1,3-dihydro-imidazole-2-selone, (seim(Mes))H, may be obtained from 1-mesitylimidazole via (i) deprotonation with (BuLi)-Li-n, (ii) treatment with elemental selenium, and (iii) addition of HCl(aq). Structural characterization of (seim(Mes))H by X-ray diffraction demonstrates that the compound exists as the selone rather than selenol tautomer, a result that is in accord with DFT calculations. Solutions of (seim(Mes))H are oxidized by air to give bis(1- mesitylimidazol-2-yl) diselenide, (seim(Mes))(2). A corresponding investigation of (seim(Me)) H demonstrates that, in contrast to a previous report, the selenium analogue of methimazole exists in the selone form with a structure analogous to that of methimazole. H-1 and Se-77 NMR studies demonstrate that the (seim(R)) groups of the selone (seim(R))H and diselenide (seim(R))(2) undergo facile exchange on the NMR time scale.

  Ni(PMe3)4 effects cleavage of the disulfide bond of (mim(Bu)(t))2 to give square-planar trans-Ni(PMe3)2(mim(Bu)(t))2 in which the (mim(Bu)(t)) ligands coordinate via nitrogen rather than sulfur, a most uncommon coordination mode for this class of ligands. Although [kappa2-(mim(R))2]MCl2 (M = Fe, Co, Ni, Zn) are not subject to homolytic cleavage of the S-S bond because the tetravalent state is not readily

  双(1-R-咪唑-2-基)二硫化物(mim(R))2 (R = Ph, Bu(t))和二硒化物(seim(Mes))2作为二齿N,N-主族金属和过渡金属的供体配体。例如，[kappa2-(mim(Bu)(t))2]MCl2 (M = Fe, Co, Ni, Zn), [kappa2-(mim(Ph))2]MCl2 (M = Co, Zn), [kappa2-(mim(Bu)(t))2]CuX (X = Cl, I) 和 [kappa2-(seim(Mes))2]MCl2 (M = Fe, Co, Ni) (mim(Bu)(t))2 或 (seim(Mes))2 与相应的金属卤化物，并已通过 X 射线衍射进行结构表征。另一方面，零价镍配合物 Ni(PMe3)4 影响 (mim(Bu)(t))2 的二硫键断裂，得到方形平面反式 Ni(PMe3)2(mim(Bu)(t) ))2 其中 (mim(Bu)(t))
