摘要：

A novel bis-styrene IPrNi0 derivative has been synthesized from the reaction of Ni(COD)(2) and free 1,3-bis(2,6-diisopropylphenyl)imidazolidene (IPr) ligand in the presence of styrene. The complex has been characterized by spectroscopic data as well as by X-ray crystallography. Its catalytic performance in the amination reaction of aryl tosylates is also reported. The catalytic reactions proceed in a very selective manner, affording moderate to high yields of cross-coupling products in short reaction times at 110 degrees C.
