  Preparation and characterisation of [Pt{N(SePPh₂)₂-Se,Se′}(PR₃)₂]Cl (R = alkyl or aryl); crystal structure of [Pd{Ph₂PNP(Se)Ph₂-P,Se}{N(SePPh₂)₂-Se,Se′}]·0.5EtOH·0.3CH₂Cl₂

  摘要：

  Reaction of NH(PPh(2))(2) with selenium gives Ph(2)P(Se)NHP(Se)Ph(2) which may be deprotonated with KOBu(t) to give K[Ph(2)P(Se)NP(Se)Ph(2)]. This can be treated with appropriate Group VIII metal complexes to give [Rh{N(SePPh(2))(2)}(cod)] (cod = cycloocta-1,5-diene), a series of complexes of formula [Pt(N(SePPh(2))(2)-Se,Se')(PR(3))(2)]Cl (PR(3) = PMe(3), PMe(2)Ph, PEt(3), PPh(3), 1/2NH(PPh(2))(2) or 1/2Ph(2)PCH(2)CH(2)PPh(2)) and [MCl{N(SePPh(2))(2)-Se,Se'}(PMe(2)Ph)] (M = Pt or Pd). The new compounds have been characterised by P-31 and Pt-195 NMR and IR spectroscopy, FAB(+) mass spectrometry and microanalyses. Furthermore, a small quantity of a mixed-ligand complex [Pd{Ph(2)PNP(Se)Ph(2)-P,Se}{N(SePPh(2))(2)-Se,Se'}]. 0.5EtOH . 0.3CH(2)Cl(2) has been characterised by X-ray crystallography and P-31 NMR spectroscopy. Its structure reveals an approximately planar five-membered PdSeP2N ring and a puckered six-membered PdSe2P2N ring. in the crystal the molecules pack with channels which contain the disordered CH2Cl2 molecules running down the a direction.

  三价A /钕分子中软-硒与硬-O供体键合的结构和光谱比较

  摘要：

  共价通常被认为是驱动软供体配体引起的An 3+对Ln 3+选择性的影响因素。对此进行了激烈的辩论，尤其是在遍历f块时，出现了3+ / Ln 3+共价差异的程度并表现出来，以及周期性中断的影响超出了Pu。在此，将两个Am络合物[Am {N（E = PPh 2）2 } 3 ]（1-Am，E = Se; 2-Am，E = O）与等径线[Nd {N（E = PPh 2））2 } 3 ]（1‐Nd，2‐Nd）复合体。评估共价贡献并将其与U / La和Pu / Ce类似物进行比较。通过基于紫外可见近红外光谱和单晶X射线结构的从头算计算，我们观察到Am-Se和Nd-Se键之间的轨道参与不同，这在O型供体同源物中不存在。

  The catalytic efficiency of the dinuclear complex depends on the cooperative effect of the TiIV ions, the systematic variation of the intermetallic distance, and the ligand’s steric properties of the complex, which enhances the reaction rate. Most interestingly, this is the first example of catalytic insertion of various E–H bonds into the carbodiimides using a single-site catalyst because only the titanium-mediated

  2′-deoxynucleosides to furanoid glycals have been discovered. These phosphorimides, (Ph2PS)2NH and (Ph2PSe)2NH, were shown to effectively mediate persilylation of 2′-deoxynucleosides allowing the elimination of the nucleobase giving the corresponding glycal. These mild conditions were demonstrated in the syntheses of glycals with various substitution patterns while minimizing the formation of undesired byproducts
