Abstract New rhodium(I) N- heterocyclic carbenecomplexes were synthesized in good yields by the reactions of rhodium dimer [Rh(OMe)COD] 2 with two equivalent of 1,3-dialkylimidazolinium chloride salts in tetrahydrofuran. All of the complexes were characterized using elemental analysis, 1 H NMR and 13 C NMR spectroscopy. These complexes were used as catalysts in the hydrosilylation of acetophenone
摘要通过铑二聚体[Rh(OMe)COD] 2与两当量的1,3-二烷基咪唑啉鎓氯化物在四氢呋喃中的反应,以高收率合成了新的铑(I)N-杂环卡宾配合物。使用元素分析,1 H NMR和13 C NMR光谱对所有配合物进行表征。这些配合物在80°C下将苯乙酮衍生物与三乙基硅烷氢化硅烷化反应中用作催化剂。这些Rh(I)-NHC配合物显示出对苯乙酮衍生物进行氢化硅烷化的良好催化性能,并且通过使用1mol%的铑配合物以中等至良好的产率获得了相应的氢化硅烷化产物。
