  Synthesis, Characterization, and Catalytic Application of Colloidal and Supported Manganese Nanoparticles

  摘要：

  Colloidal and supported manganese nanoparticles were synthesized following an organometallic approach and applied in the catalytic transfer hydrogenation (CTH) of aldehydes and ketones. Reaction parameters for the preparation of colloidal nanoparticles (NPs) were optimized to yield small (2–2.5 nm) and well‐dispersed NPs. Manganese NPs were further immobilized on an imidazolium‐based supported ionic phase (SILP) and characterized to evaluate NP size, metal loading, and oxidation states. Oxidation of the Mn NPs by the support was observed resulting in an average formal oxidation state of +2.5. The MnOx@SILP material showed promising performance in the CTH of aldehydes and ketones using 2‐propanol as a hydrogen donor, outperforming previously reported Mn NPs‐based CTH catalysts in terms of metal loading‐normalized turnover numbers. Interestingly, MnOx@SILP were found to lose activity upon air exposure, which correlates with an additional increase in the average oxidation state of Mn as revealed by X‐ray absorption spectroscopic studies.

  homogeneous catalyst in numerous reactions. Herein, the preparation of silica-supported MnII sites is reported using Surface Organometallic Chemistry (SOMC), combined with tailored thermolytic molecular precursors approach based on Mn2 [OSi(OtBu)3 ]4 and MnN(SiMe3 )2 }2 ⋅THF. These supported MnII sites, free of organic ligands, efficiently catalyze numerous reactions: hydroboration and hydrosilylation of ketones

  锰是仅次于铁和钛的第三大过渡金属元素，最近已证明在许多反应中都是有效的均相催化剂。本文中，报道了使用表面有机金属化学（SOMC）结合基于Mn2 [OSi（OtBu）3] 4和Mn N（SiMe3）2} 2⋅THF的量身定制的热解分子前体方法，制备了二氧化硅负载的MnII位点的方法。 。这些支持的MnII位点没有有机配体，可有效催化众多反应：酮和醛的硼氢化和氢化硅烷化以及工业相关底物的酯交换反应。

  [Mn(NSiMe3}2)2(C4H8O)] with two equivalents of HSC6H3-2,6-(SiMe3)2 in n-pentane leads to the formation of [Mn2(SC6H3SiMe3}2)4(C4H8O)] which was isolated as the mono-pentane solvate. According to the results of an X-ray structure determination, this binuclear complex contains both trigonally and tetrahedrally coordinated manganese sites simultaneously and thus is a rare example of complexes which
