在这项工作中,我们表明碲酸锂Li(X)nTeCH 2SiMe 3(X = THF,n = 1,1; X = 12-冠-4,n = 2,2),可以作为一个有效的Te原子转移试剂的所有第5族过渡金属卤化物前体,而不管氧化态。本文报道了一碲化物和双碲化物配合物,即(PNP)M(Te)2(M = V; Nb,3; Ta,4; PNP− = N[2-PiPr 2 -4-methylphenyl]2),包括结构和光谱数据。而已知的络合物(PNP)V(Te)_2可以容易地从三价前体(PNP)VCl_2制备,两当量的(PNP)V(Te)_2的量为1000克。的碲酸盐和用PMe 3部分增溶的元素Te,配合物3也可以按照相同的程序类似地获得,但有或没有还原剂Na/NaCl。另一方面,配合物4是由四个当量的加成形成的。将碲酸盐转化为(PNP)TaF 4。获得了第5族金属的(PNP)M(Te)2系统的三元组,使我们能够使用理论和光谱(包括Te-L1边缘XANES数据)的组合来比较它们。在这项工作中,我们表明碲酸锂Li(X)nTeCH 2SiMe 3(X = THF,n = 1,1; X = 12-冠-4,n = 2,2),可以作为一个有效的Te原子转移试剂的所有第5族过渡金属卤化物前体,无论其氧化态。
We show in this work how lithium tellurolate Li(X)nTeCH2SiMe3 (X = THF, n = 1, 1; X = 12-crown-4, n = 2, 2), can serve as an effective Te-atom transfer reagent to all group 5 transition metal halide precursors irrespective of the oxidation state. Mononuclear and bis(telluride) complexes, namely (PNP)M(Te)2 (M = V; Nb, 3; Ta, 4; PNP− = N[2-PiPr2-4-methylphenyl]2), are reported herein including structural and spectroscopic data. Whereas the known complex (PNP)V(Te)2 can be readily prepared from the trivalent precursor (PNP)VCl2, two equiv. of tellurolate, and elemental Te partially solubilized with PMe3, complex 3 can also be similarly obtained following the same procedure but with or without a reductant, Na/NaCl. Complex 4 on the other hand is formed from the addition of four equiv. of tellurolate to (PNP)TaF4. Having access to a triad of (PNP)M(Te)2 systems for group 5 metals has allowed us to compare them using a combination of theory and spectroscopy including Te-L1 edge XANES data. We show in this work how lithium tellurolate Li(X)nTeCH2SiMe3 (X = THF, n = 1, 1; X = 12-crown-4, n = 2, 2), can serve as an effective Te-atom transfer reagent to all group 5 transition metal halide precursors irrespective of their oxidation state.
