The reaction of Ni（PMe3）4 and Ni（PMe3）2（COD） with substituted benzonitriles lead to C-C bond cleavage under mild conditions. And we attempted the reactions of benzonitrile nickel（Ⅱ） complexes with bromobenzene and carbon monoxide,respectively.4.

本课题利用零价镍配合物Ni（PMe3）4和Ni（PMe3）2（COD）分别与取代苯甲腈的反应,在较温和的条件下实现了C-CN键的活化,并初步探讨了腈基镍配合物与溴苯和CO等的反应性能。

Bromobenzene widely exists as one of the organic pollutant in waters. It is one of the organic intermediates in chemical synthetical processes and the representation of halogenated aromatics and organic solvent.

溴苯作为水体中常见的有机污染物之一在环境中广泛存在,它是许多化学合成的有机中间体,也是有机溶剂与卤代芳香族物质的代表,给环境和人体健康带来不容忽视的危害。
