摘要
A [Pd（1-tritylimidazole）2Cl2] complex was synthesized and characterized by IH and 13C NMR spectroscopy, elemental analysis, and X-ray crystallography. The X-ray analysis confirmed that the Pd（II） has a four-coordinated square planar structure. The palladium complex was used to carry out Suzuki-Miyaura coupling reactions of aryl chlorides with a variety of phenylboronic acids in i-PrOH-H20 （1 ： 1, V ： V） at room temperature and Heck coupling reactions of aryl halides with methyl acrylate in DMF at 110℃. High yields of the cross-coupling products were obtained.
