  描述：

  methoxy(cyclooctadiene)rhodium(I) dimer 、 1-isopropyl-3-(3,4,5-trimethoxybenzyl)benzimidazolium chloride 以 四氢呋喃 为溶剂， 反应 5.0h， 以82%的产率得到[1-(3,4,5-trimethoxybenzyl)-3-(isopropyl)]-benzimidazolin-2-ylidene-[(1,2,5,6-η⁴)-1,5-cyclooctadiene]chlororhodium(I)

  名称：

  Synthesis of rhodium complexes derived from benzimidazolin-2-ylidene ligands and first used for the addition of arylboron to benzonitriles

  摘要：

  Benzimidazolium salts and their new rhodium complexes ([RH(COD)(NHC)Cl]) were synthesized and characterized by elemental analysis, H-1 NMR, C-13 NMR, and IR spectroscopy. The addition of arylboron to benzonitriles in the presence of a catalytic amount of rhodium NHC complexes was examined. Corresponding carbonyl compounds were obtained in good yields. This method allows for the preparation of a wide variety of carbonyl compounds in moderate to excellent yields and displays a high level of activity for the addition of arylboron to nitriles.
