efficient (>40 % yield) through the reaction of 1,1′-dilithioferrocene with MeAlCl2. The molecular structures of the dinuclear and trinuclear complexes were determined by X-ray crystallography. The solution-state structures of the new compounds were studied by multinuclear magnetic resonance methods, including 1H–1H NOE difference experiments.(© Wiley-VCH Verlag GmbH & Co.

在 1,1'-位带有二烷基铝取代基的
二茂铁被表征为它们的二
吡啶加合物,并且表明它们可以转化为双核烷基铝桥接的 [1.1]
二茂铁,最后转化为三核铝桥接的
二茂铁,两者均为双
吡啶加合物。通过 1,1'-二
硫代
二茂铁与 MeAlCl2 的反应,优化后一种化合物的合成并发现其最有效(>40% 产率)。双核和三核复合物的分子结构由 X 射线晶体学确定。通过多核磁共振方法研究了新化合物的溶液态结构,包括 1H–1H NOE 差异实验。 (© Wiley-
