At the right places: Owing to substitution-lability difference in disparate metal centers, an oxo-centered heterometallic trinuclear acetato complex [Ru2MgO(CH3COO)6(py)3] (py = pyridine; see picture) undergoes site-selective substitution of propionates and ferrocenycarboxylates in a stepwise manner. The new substituted families have been successfully separated by chromatography and fully characterized.
由于不同金属中心的取代位阻差异,一个氧中心的异金属三核乙酰丙酮配合物[Ru2MgO(CH3COO)6(py)3](py=吡啶;见图片)以分步的方式进行丙酸盐和二茂铁羧酸根的位选择性取代。新的取代族已通过色谱法成功分离并进行了充分的表征。
