<P>PROBLEM TO BE SOLVED: To provide a polymer fixed transition metal catalyst fixing an organic polymer with a transition metal, having high activity, and easy in recovery and reuse. <P>SOLUTION: Various transition metals are carried by polysilane, or a polysilane compound and an inorganic compound by combining a microencapsulation method with ligand exchange or reduction operation using the polysilane compound, or the poly silane compound and the inorganic compound. Polysilane carried with the transition metal can easily be cured by heating, microwave irradiation, ultraviolet irradiation or a chemical method such as a hydrosilylation reaction, and is insoluble to various solvents while maintaining the activity of a catalyst. Further, carrying this polysilane-carrying transition metal catalyst on the inorganic compound enhances stability and operability. These polysilane-carrying transition metal catalysts exhibit high activity to a hydrogenation reaction, the hydrosilylation reaction, a Heck reaction, a Suzuki-Miyaura coupling reaction or the like, are easy in recovery and reuse, and are extremely small in metal leakage. <P>COPYRIGHT: (C)2008,JPO&INPIT |
