过渡金属硅卡拜、锗卡拜、锡卡拜和铅卡拜是过渡金属分别与硅、锗、锡和铅之间形成三键的化合物。自从1996年首次发现钼锗卡拜以来,相继得到了一系列过渡金属锗卡拜、锡卡拜和铅卡拜化合物,而首例过渡金属硅卡拜则于2010年得以成功制备,标志着过渡金属与第14族元素之间形成三键的空白被全部填满。这些化合物的出现大大丰富和完善了过渡金属主族元素化学在成键、结构和反应方面的内容,引起化学界的重视。本文结合这方面最新的实验研究进展,系统全面总结了这些化合物的合成、结构和反应性,并对该领域的发展前景作了讨论。
Transition metal silicon kay, germanium kay, kay, kay, kayak and lead are the transition metals that form triple bonds with silicon, germanium, tin and lead, respectively. Since the discovery of molybdenum and germanium kayaking for the first time in 1996, a series of transition metal germanium kerosene, tin carbay and lead carbazole compounds have been successively obtained, while the first transition metal silicon carbazole was successfully prepared in 2010, marking the transition The space between the metal and the Group 14 element that forms the triple bond is completely filled. The emergence of these compounds greatly enriched and perfected the main elements of transition metal chemistry in the bonding, structure and reaction content, aroused the attention of the chemical community. In this paper, the latest advances in experimental research in this area, a comprehensive summary of the synthesis of these compounds, structure and reactivity, and the development of the field are discussed.
