発明の名称 (英語) Microencapsulated metal catalyst
発明の概要(英語) (US7307193)
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.
特許請求の範囲(英語) [claim1]
1. A method for allylation reaction, which comprises reacting a C-nucleophile and an allylic carbonate in the presence of a microencapsulated metal catalyst in which a metal catalyst containing palladium is 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 palladiunm.
[claim2]
2. The method of claim 1, wherein the reaction is performed in the presence of the microrncapsulated triphenyiphosphine metal catalyst Pd(PPh3) and an external ligand.
[claim3]
3. A method for asymmetric synthesis reaction, which comprises reacting a C-nucleophile and an allylic carbonate in the presence of a microencapsulated metal catalyst in which a metal catalyst containing palladium is encapsulated in a polymer that has side chains containing an aromatic substituent, and a chiral ligand, wherein the metal catalyst is a triphenylphosphine metal catylst represented by the following general formula (I);

M(PPh3) (I)
wherein M represents Dalladium.
[claim4]
4. The method of claim 1, wherein the polymer that has side chains containing an aromatic substituent is a polymer having styrene units.
[claim5]
5. The method of claim 3, wherein the polymer that has side chains containing an aromatic substituent is a polymer having styrene units.
