Abstract
The CC coupling of aryl nitriles at Group 4 metallocenes leads to unusual ring-strained 1-metalla-2,5-diaza-cyclopenta-2,4-dienes. The structural, energetic, and chemical properties of these complexes are described. The reactions of these compounds towards CH3 CN, H2 , CO2 , and HCl usually lead to the release of one nitrile and its replacement by different co-substrates.
摘要
芳基腈在第 4 族金属茂中的 CC 偶联导致了不寻常的环张力 1-金属-2,5-二氮杂环戊-2,4-二烯。这些配合物的结构、能量和化学性质都进行了描述。这些化合物与 CH3 CN、H2 、CO2 和 HCl 的反应通常会导致一个腈的释放，并被不同的共底物取代。
