摘要

在這篇報告中我們將探討三核及四核異金屬炔類錯合物，LWOs_3(CO)_(11)(C≡CR)及LWM_2(CO)_8(C≡CR)，L=Cp及Cp；M=Os及Ru，的合成、特性及反應性，尤其是與雙取代炔類分子的反應。另外，乙烯基炔類錯合物Cp﹒WRe_2(CO)_9[C≡CC(Me)=CH_2]與醇類及氫分子的反應特性也將一併提出討論。

並列摘要

The chemistry of trinuclear and tetranuclear heterometallic acetylide complexes, LWOS_8(CO)_(11)-(C≡CR) and LWM_2(CO)_8(C≡CR), L=Cp and Cp; M=Os and Ru, is presented. Included in this account are syntheses, characterization and reactivity, with a particular focus on reactions with disubstituted alkyne molecules. The reactivity and fluxionality of these acetylide complexes provides a plausible model for ligand-mediated metal-core rearrangement and the transformation of small organic molecules on catalytic metal surfaces. Finally, study on the related Cp WRe_2(CO)_9(C≡CR) is also discussed.
