Title:
NITROGEN HETEROCYCLIC CARBENE LIGANDS AND RUTHENIUM CATALYSTS THEREOF, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/140441
Kind Code:
A1
Abstract:
The invention relates to nitrogen heterocyclic carbene ligands and ruthenium catalysts thereof, a preparation method therefor and an application thereof. The structures of the nitrogen heterocyclic carbene ligands are represented by formulas Ia and Ib, respectively, and the corresponding ruthenium catalyst structures are represented by IIa and IIb, respectively. After simultaneously introducing large-steric hindrance and electron-rich groups into the described nitrogen heterocyclic carbene ligand structures, the catalytic activity, stability and application range of the ruthenium complex catalysts thereof are significantly improved.
