![عکس صفحه اول مقاله: Effective heterogenization and catalytic use of active C5H5 NiLX complex for the hydrosilylation Effective heterogenization and catalytic use of active C5H5 NiLX complex for the hydrosilylation](/preview/png/53078.png)
An effective route was first developed to heterogenize active C5H5NiLX complex for the preparation of the solid catalyst . The attachment of the nickel complex onto the polymer was carefully characterized by IR, solid diffuse reflectance UV–vis, 31P CP MASNMR spectra and ICP-OES elemental analysis, which proved that the present route was relatively simple and effective for the immobilization of active centers, and that the materials used was considerably cheap. Thus-prepared solid catalyst showed high activity, selectivity and an excellent recyclability for the hydrosilylation of alkenes with trichlorosilane at mild conditions, outstandingly overcoming the problem of homogeneous system. This is a key success to provide a new methodology for heterogenizing active homogeneous components.
