Title Microencapsulated metal catalyst
Abstract (US7488698)
A microencapsulated Group VIII metal catalyst which is stable even in air, easy to recover, and reusable is disclosed.
It comprises a polymer with side chains containing an aromatic substituent, and a metal catalyst comprising a Group VIII metal encapsulated in to this polymer.
Scope of claims [claim1]
1. A microencapsulated metal catalyst, which comprises a metal catalyst containing palladium encapsulated in a polymer that has side chains containing an aromatic substituent, wherein the metal catalyst is a triphenylphosphine metal catalyst represented by the following general formula (I):
M(PPh3) (I)wherein M represents palladium.
[claim2]
2. The microencapsulated metal catalyst of claim 1, wherein the polymer that has side chains containing an aromatic substituent is a polymer having styrene units.
[claim3]
3. The microencapsulated metal catalyst of claim 2, wherein the polymer that has side chains containing an aromatic substituent is polystyrene.
