Title:
METHOD FOR COUPLING ORGANIC SODIUM COMPOUND AND ORGANIC CHLORIDE
Document Type and Number:
WIPO Patent Application WO/2020/246545
Kind Code:
A1
Abstract:
To construct a technique capable of coupling efficiently using only metal species that are inexpensive and excellent in terms of sustainability in a method for cross-coupling an organic halogen compound and an organometallic compound in the presence of a metal catalyst. A method for coupling an organic sodium compound and an organic chloride that includes a step for reacting an organic sodium compound and an organic chloride in a reaction solvent in the presence of a metal catalyst containing one or more first transition metals selected from atomic numbers 24-28 to obtain a coupling product by coupling the organic sodium compound and organic chloride.
