Abstract

A highly efficient catalytic system for the aerobic oxidative cleavage of vicinal diols has been developed based on CuCoFe metahydrotacite-B, without the requirement of any additives. The electron density of the Co²⁺ sites is increased in the presence of Cu and Fe species, which can enhance the activity of the key intermediates Co³⁺OO·. The appropriate surface acidity and basicity of the catalyst based on the metahydrotacite-B phase effectively improve selectivity. The reaction system can tolerate various vicinal diols, and a distinctive reaction path has been proposed.

在CuCoFe偏氢乙酸乙酯- b中构建的高活性Co2+物质实现了邻二醇的高效氧化裂解，无需任何添加剂

以CuCoFe偏氢乙酸乙酯- b为原料，研制了一种不需要任何添加剂的邻苯二醇有氧氧化裂解的高效催化体系。Cu和Fe的存在增加了Co2+位的电子密度，增强了关键中间体Co3+OO·的活性。偏氢乙酸- b相催化剂表面适宜的酸碱度可有效提高催化剂的选择性。该反应体系能耐受多种邻二醇，并提出了独特的反应路径。

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
