  6]‐closed and [6,6]‐open structures were characterized for the SHC adducts of C60 and Sc3N@Ih‐C80, respectively. These derivatives exhibited relatively low oxidation potentials, indicative of the electron‐donating effects of the SHC addends. The electronic properties of the SHC derivatives were clarified by the density functional theory calculations.

  The addition of a series of primary and secondary amides to the group 14 (di)metallenes Mes2SiSiMes2, Mes2GeGeMes2 and (Me3Si)2SiC(OSiMe3)R, where R = t-Bu or R = 1-Ad, was examined. In general, the addition of primary and N-methyl amides gave amide adducts whereas the addition of N-phenyl amides gave imidate adducts. The regiochemistry of the additions was highly dependent upon the substituent bonded to the amide nitrogen. We propose that the formation of the adducts proceeds by way of a zwitterionic intermediate. The reactivity of tetramesityldigermene towards amides is used to predict the structure of the amide adducts formed on the Ge(100)-2 × 1 surface.

  将一系列伯酰胺和仲酰胺加成到14族（双）金属烯Mes2SiSiMes2、Mes2GeGeMes2和(Me3Si)2SiC(OSiMe3)R（其中R=t-Bu或R=1-Ad）的过程已被探究。一般来说，伯酰胺和N-甲基酰胺的加成会得到酰胺加合物，而N-苯基酰胺的加成则会得到亚胺酸酯加合物。加成的区域化学性质高度依赖于与酰胺氮原子连接的取代基。我们提出，加合物的形成是通过两性离子中间体的途径进行的。通过四二甲苯二锗的酰胺反应活性，预测了在Ge(100)-2×1表面上形成的酰胺加合物的结构。

  On irradiation, dibenzo-7-silanorbornadienes with bulky substituents on silicon generated the corresponding crowded silylenes that dimerized to kinetically stable disilenes in the absence of trapping agents. Dibenzo-7-silanorbornadienes also underwent a new type of photochemical isomerization competitively.

  (RN3) with tetramesityldisilene (1) were studied. Azides with R = Ph or Mes each gave two products, a disilaaziridine and a disilatriazoline. When R = PhCH2 or Me3SiCH2 intermediate adducts of the azide and the disilene were found. These adducts and the disilatriazolines both react thermally to yield the respective disilaaziridines. For R = Me3Si only a disilaaziridine was observed, the structure of which

  研究了几种有机叠氮化物（RN 3）与四甲叉二烯（1）的反应。R = Ph或Mes的叠氮化物各自提供两种产物，二硅氮杂吡啶和二硅三唑啉。当R ＝ PhCH 2或Me 3 SiCH 2时，发现叠氮化物和二烯的中间加合物。这些加合物和二硅三氮唑啉都热反应以产生各自的二硅氮丙啶。对于R ＝ Me 3 Si，仅观察到二硅氮丙啶，其结构通过X射线晶体学测定，发现具有短的Si 3 Si核间距离为2.23。晶体数据：R =三甲基甲硅烷基，a 23.561（3），b 19.001（3），c16.916（3）Å，单斜晶，β= 106.095°，C 2 / c，Z =8。从1与甲苯磺酰基叠氮化物和二苯基膦酰基叠氮化物的反应中分离出新型五元硅杂环。
