new dithiatellura-macrocycles have been investigated with a variety of transition metal species giving fac-[Mn(CO)3(L)]CF3SO3, cis-[MCl2(L)] (M = Pd or Pt), [Rh(Cp*)(L)](PF6)2, [Cu(L)]BF4 and [Ag(L)]CF3SO3. Where possible, the mode of coordination has been established by spectroscopic methods, ring-size effects established and the data compared with other complexes incorporating related cyclic and
Na 2 Te与各种α,ω-二氯二硫醚试剂在thf–中的反应NH 3(L)在约 −78°C产生[1 + 1]环化产物[9] aneS 2 Te(1,4-二硫杂-7-碲环壬烷),[11] aneS 2 Te(1,4-二硫-8-碲环十一烷)和[12] aneS 2 Te(1,5-二硫一9-碲环十二烷), 和...一起 聚合物。这些新的小戒指大环 可以通过闪光灯纯化 柱层析 在 硅石 (11元和12元环)或 重结晶 从 甲醇–thf(9元环),提供黄色蜡状固体。该产品的特点是核磁共振(1 H,13 C 1 H}和125 Te 1 H})和红外光谱, 质谱得到[11] aneS 2 Te和[12] aneS 2 Te的晶体结构。更稳定的有机碲(IV)的衍生物[ Ñ ] ANES 2的Tel 2 (Ñ = 11或12)和[ Ñ ] ANES 2 TeMeI(Ñ = 9,11或12)以高收率由反应粉状固体获得I
