Title:
CARBOHYDRATE MONOPHOSPHINES, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/073657
Kind Code:
A1
Abstract:
Provided by the present invention are carbohydrate monophosphines represented by general formula Ia, Ib, IIa or IIb, comprising mixtures represented by Ia and Ib having different phosphorus atom configurations, or mixtures represented by IIa and IIb having different phosphorus atom configurations, and a method for preparing same; the present invention describes borane adducts, oxides, sulfides or selenides of the carbohydrate monophosphines; in addition, further provided by the present invention is a palladium complex complexed with a carbohydrate monophosphine; a catalytic system composed of a carbohydrate monophosphine and palladium salt or a complex thereof, or a use of a palladium complex complexed with a carbohydrate monophosphine in catalyzing organic reactions is also a part of the present invention, in particular a use in catalyzing coupling reactions of (pseudo) haloaromatics to form new C-C or C-N bonds.
