(1) A catalyst composition comprising a crosslinked organic polymer and a palladium catalyst, wherein the catalyst is physically supported on the crosslinked organic polymer; (2) a process for producing the catalyst composition (1), characterized by evenly mixing a linear organic polymer having crosslinkable functional groups with a palladium catalyst in a solvent in which the linear organic polymer is soluble, subsequently precipitating the resultant composition, and causing the crosslinkable functional groups contained in the precipitate to undergo a crosslinking reaction; (3) a method of allyl-position-shifting reaction, characterized by causing a nucleophilic agent to act on an allylcarbonic ester in the presence of the catalyst composition (1); and (4) a method of alcohol oxidation, characterized by causing the catalyst composition (1) to act on an alcohol. The catalyst composition has no fear of spontaneous ignition and can be handled safely and easily. It is extremely useful as a catalyst for various chemical reactions. It undergoes no decrease in activity even when used repeatedly. The metal catalyst is not released from the polymer support. |
