Abstract
A macromolecules containing a metal and a use thereof as a catalyst are disclosed. The macromolecules containing a metal may be obtained by causing a ligand to react with a zinc compound or a cobalt compound. The ligand has an imidazole group that is bonded to a macromolecule via a linker. The metal-containing macromolecules are highly active as a catalyst, stable, and easy to recover and reuse.
Claims2
A polymer-supported metal, said metal being zinc, obtained by reacting, in a solvent, a zinc compound with a polymer of the following general formula (I):
- wherein
- Polymer represents a polymer backbone,
- L represents a linker,
- n represents a natural number,
- wherein a ratio of imidazolyl groups in the polymer (I) relative to zinc atoms is 4 to 8, and the imidazolyl group content in the polymer (I) is 1.25 mmol/g to 1.85 mmol/g.
