  Synthesis and crystal structure of tetrakis(2,4,6-trimethylphenyl)dibismuthoxide

  摘要：

  Bis(2,4,6-trimethylphenyl)chlorobismuth (1), synthesized by comproportionation reaction of tris(2,4,6-trimethylphenyl)bismuth and bismuth chloride, was reduced with sodium in liquid ammonia. By subsequent insertion of oxygen into the Bi-Bi bond of the intermediate dimer tetrakis(2,4,6,-trimethylphenyl)dibismuth the title compound (2) was formed whose crystal structure has been determined: [monoclinic, space group P2(1)/n; a = 12.225(1) Angstrom; b = 14.957(1) Angstrom; c = 18.531(1) Angstrom; beta = 97.76(1)degrees; Z = 4]. (2) shows a Bi-O-Bi bond angle of 124.6 degrees and a short intramolecular nonbonding Bi ... Bi distance of 3.665 Angstrom, probably the inherent reason for the metallic colour of (2).

  Palladium(II)-Catalyzed Aryl Coupling of Triarylbismuthines under Air

  摘要：

  三芳基铋烷在空气中与催化量的醋酸钯(II)在甲醇中迅速反应，生成相应的双芳烃，产率很高。氧的存在对这种催化偶联反应是不可或缺的，因为在氮气环境下双芳烃的形成相当缓慢。在反应过程中观察到了氧的吸收，另外制备的钯-氧复合物即使在惰性气体下也能有效作为该偶联反应的试剂。

• Activity of Antifungal Organobismuth(III) Compounds Derived from Alkyl Aryl Ketones against S. cerevisiae: Comparison with a Heterocyclic Bismuth Scaffold Consisting of a Diphenyl Sulfone

  A series of hypervalent organobismuth(III) compounds derived from alkyl aryl ketones [XBi(5-R'C6H3-2-COR)(Ar)] was synthesized to investigate the effect of the compounds' structural features on their antifungal activity against the yeast Saccharomyces cerevisiae. In contrast to bismuth heterocycles [XBi(5-RC6H3-2-SO2C6H4-1'-)] derived from diphenyl sulfones, a systematic quantitative structure-activity

  合成了一系列衍生自烷基芳基酮 [XBi(5-R'C6H3-2-COR)(Ar)] 的高价有机铋 (III) 化合物，以研究这些化合物的结构特征对其抗酵母菌活性的影响酿酒酵母。与衍生自二苯砜的铋杂环 [XBi(5-R -2-SO2 -1'-)] 相比，系统的定量构效关系研究是可能的。活性取决于 Ar 基团，对于较重的 X 原子会增加，而延长烷基链 (R) 或引入取代基 (R') 会降低活性。IBi(C6H4-2-CO )(4-F ) 是最活跃的。其活性优于相关的无环类似物 ClBi[ -2-CH2N(CH3)2](Ar) 和 ClBi( -2-SO2 tert-Bu)(Ar)，也可与杂环 ClBi( -2-SO2 -1'-)，这是我们之前研究中最活跃的化合物。密度函数理论计算表明，高价铋烷与铋原子上的生物分子发生亲核加成，得到中间体 ate 络

  Investigations on the boundaries between the neutral and cationic models of (Mesityl)2EX (E = Sb, Bi and X = Cl−, OTf−) have facilitated reversing the Lewis acidity from bismuth to antimony. We use this concept to demonstrate a higher efficiency of (Mesityl)2SbOTf over (Mesityl)2BiOTf in the catalytic reduction of phosphine oxides to phosphines. The experiments supported with computations described

  对 (Mesityl) 2 EX (E = Sb, Bi 和 X = Cl - , OTf - )的中性和阳离子模型之间边界的研究促进了路易斯酸度从铋到锑的逆转。我们使用这个概念来证明 ( Mesityl ) 2 SbOTf 比 ( Mesityl ) 2 BiOTf 在将氧化膦催化还原为膦方面的效率更高。此处描述的计算所支持的实验将用于设计与催化相关的新路易斯酸。

  The threefold cross-coupling reactivity of sterically highly demanding bulky triarylbismuths was addressed with task specific Pd–Cu dual catalytic conditions. In this study, an unprecedented hitherto unknown cross-coupling reactivity of sterically bulky triarylbismuths was demonstrated with a diverse range of aryl iodides and bromides. The intermediacy and in situ formation of arylcopper was probed
