Effective heterogenization and catalytic use of active C5H5 NiLX complex for the hydrosilylation

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.
