  摘要：

  Treatment of donor-substituted acetylenes (X-CdropC-X, with X = R-Se, R-Te) with sodium trichloroacetate, followed by hydrolysis, yielded the corresponding cyclopropenones. Their structures could be elucidated by X-ray analysis, and indicated significant overlap between the p-type lone pairs on the chalcogen atoms and the cyclopropenone unit. DFT calculations were carried out on various conformers in order to clarify their relative energy profiles. Methanolysis of these ring systems at room temperature quantitatively afforded alpha,beta-unsaturated esters. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003).

  [η2-Bis(tert-butylsulfonyl)acetylene](carbonyl)(η5-trimethylsilylcyclopentadienyl)cobalt (2c) proved to be reactive towards bis(telluro)- and bis(seleno)-substituted alkynes 3 and 4, respectively, to yield push-pull-substituted CpCo-stabilized cyclobutadiene complexes. By utilizing the unsymmetrical diyne 6 and the symmetrical bis(thio)-substituted triyne 7 it was shown that only the most electron-rich

  [η2-双（叔丁基磺酰基）乙炔]（羰基）（η5-三甲基甲硅烷基环戊二烯基）钴 (2c) 被证明分别对双（碲）和双（硒）取代的炔烃 3 和 4 具有反应性，以产生推动-pull 取代的 CpCo 稳定的环丁二烯配合物。通过利用不对称的二炔 6 和对称的双（硫代）取代的三炔 7，表明只有最富电子的三键才会被亲电子化合物 2c 攻击。在7的情况下，获得了由一个乙炔部分桥接的双核CpCo稳定的环丁二烯配合物14。所有的反应都可以在相当温和的条件下在室温下进行。8、12、14a 和 15 的 X 射线研究表明，环丁二烯部分中的 C-C 键长度几乎相等。(© Wiley-VCH Verlag GmbH & Co.

• An alkynyltelluronium iodide and its solid state structure: evidence for p→σ* interactions

  日期：2004.2

  The synthesis of the first alkynyltelluronium salt is presented. X-ray investigations of this species reveal a two-dimensional polymeric structure, assembled through various secondary (TeTe)-Te-... and (TeI)-I-... interactions. The structure itself can be rationalized in terms of P-->sigma* interactions. (C) 2003 Elsevier B.V. All rights reserved.
