摘要

几种钨羰基配合物:W(CO)6， [NEt4] [W(CO)5Cl]， [W(CO)4) (CH3CN)2]， [W(CO)4(pip)2]， [W(CO)4(bpy)]， [W(CO)4(dppe)]和[WCl2(CO)3(PPh3)2]在ZrCl4存在下对苯乙炔(PA)的聚合表现出催化活性。它们使PA在温和的条件下聚合，得到可溶的、高分子量的聚合物。由简单羰基配合物与游离炔经炔-偏乙烯重排制得含活性碳催化剂。

Polymerization of phenylacetylene by Lewis acid activated tungsten carbonyl complexes

Several tungsten carbonyl complexes: W(CO)₆, [NEt₄] [W(CO)₅Cl], [W(CO)₄) (CH₃CN)₂], [W(CO)₄(pip)₂], [W(CO)₄(bpy)], [W(CO)₄(dppe)] and [WCl₂(CO)₃(PPh₃)₂] exhibit catalytic activity towards polymerization of phenylacetylene (PA) in the presence of ZrCl₄. They cause PA to polymerize under mild conditions, giving soluble, high molecular weight polymers in good yields.

An active carbene-containing catalyst can be generated from a simple carbonyl complex and free alkyne via the alkyne to vinylidene rearrangement.

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.
