摘要

将K2ReCl6吸附在MgO粉上，通过还原羰基化法制备负载型三羰基铼。MgO上的K2ReCl6在350℃的ch3oh饱和CO中处理，形成[Re(CO)3{HOMg}x{OMg}3-x]，其中括号表示终止MgO体的基团，红外光谱证实了这一点。该合成方法是已知的制备负载型铼亚羰基最简单的方法。

Formation of rhenium subcarbonyls on magnesium oxide from adsorbed K2ReCl6

Supported rhenium tricarbonyls were prepared by reductive carbonylation of K₂ReCl₆ adsorbed on MgO powder. K₂ReCl₆ on MgO was treated at 350°C in CH₃OH-saturated CO, leading to the formation Of [Re(CO)₃{HOMg}_x{OMg}_3-x], where the braces denote groups terminating the bulk MgO, as evidenced by infrared spectra. The synthesis is the simplest known for preparation of supported rhenium subcarbonyls.

期刊介绍： Journal of Molecular Catalysis (China) is a bimonthly journal, founded in 1987. It is a bimonthly journal, founded in 1987, sponsored by Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, under the supervision of Chinese Academy of Sciences, and published by Science Publishing House, which is a scholarly journal openly circulated both at home and abroad. The journal mainly reports the latest progress and research results on molecular catalysis. It contains academic papers, research briefs, research reports and progress reviews. The content focuses on coordination catalysis, enzyme catalysis, light-ribbed catalysis, stereochemistry in catalysis, catalytic reaction mechanism and kinetics, the study of catalyst surface states and the application of quantum chemistry in catalysis. We also provide contributions on the activation, deactivation and regeneration of homogeneous catalysts, solidified homogeneous catalysts and solidified enzyme catalysts in industrial catalytic processes, as well as on the optimisation and characterisation of catalysts for new catalytic processes. The main target readers are scientists and postgraduates working in catalysis in research institutes, industrial and mining enterprises, as well as teachers and students of chemistry and chemical engineering departments in colleges and universities. Contributions from related professionals are welcome.
