A simple new route to access heterometallic alkoxo precursors for a wide range of materials is reported. This unique synthetic method comprises elimination of the cyclopentadienyl ring from Cp2MCl2 (M = Ti, Zr) as CpH in the presence of M'(OR)2 (M' = Ca, Mn; OR = OCH2CH2OCH3 or OEt) in an alcohol as a source of protons. In one-pot reactions, we have prepared four different compounds with Ti2Ca4(mu6-O), Cp2Zr2Ca4(mu4-Cl), Zr10Mn10(mu3-O) 14, and Cp3Ti2(mu-OEt)2 motifs. The compounds were characterized by single-crystal X-ray structural analysis and NMR spectroscopy.
报道了一种用于制备多种材料的异金属烷氧基前体的简单新途径。这种独特的合成方法包括在作为质子源的醇中，在M'(OR)2（M' = Ca、Mn；OR = OCH2CH2OCH3或OEt）存在下，将Cp2MCl2（M = Ti、Zr）中的环戊二烯基环作为CpH消除。在一锅反应中，我们制备了具有Ti2Ca4(μ6-O)、Cp2Zr2Ca4(μ4-Cl)、Zr10Mn10(μ3-O)14和Cp3Ti2(μ-OEt)2结构单元的四种不同化合物。通过单晶X射线结构分析和核磁共振光谱对这些化合物进行了表征。
