Document Type and Number:
WIPO Patent Application WO/2024/060641
Kind Code:
A1
Abstract:
The present invention provides a cyclotriarylphosphine ligand represented by general formula (I), and a method for preparing same. The present invention also provides a complex of palladium in coordination with the cyclotriarylphosphine ligand. A catalytic system consisting of the cyclotriarylphosphine ligand and a palladium salt or the complex and use of the palladium complex thereof in catalyzing an organic reaction, in particular use in catalyzing a coupling reaction involving a (pseudo) halogenated aromatic hydrocarbon as the substrate, are also parts of the present invention.
