Disclosed is a polymer-immobilized transition metal catalyst in which a transition metal is immobilized on an organic polymer and is highly active and easy to recover and reuse. SOLUTION: A polysilane compound or a polysilane compound and an inorganic compound are used as a polymer carrier, and various transition metals are supported on the polysilane or the polysilane compound and the inorganic compound by combining a microencapsulation method and a ligand exchange or a reduction operation. It was done. The polysilane carrying a transition metal can be easily crosslinked by a chemical method such as heating, microwave irradiation, ultraviolet irradiation, or hydrosilylation reaction, and becomes insoluble in various solvents while retaining its catalytic activity. Furthermore, stability and operability are improved by supporting the polysilane-supported transition metal catalyst on an inorganic compound. These polysilane-supported transition metal catalysts exhibit high activity for hydrogenation reaction, hydrosilylation reaction, Heck reaction, Suzuki-Miyaura coupling reaction, etc., are easy to recover and reuse, and have very little metal leakage.
