Title:
METHOD FOR SYNTHESIZING ORGANIC MAGNESIUM COMPOUND, METHOD FOR SYNTHESIZING ORGANIC BORIC ACID COMPOUND, AND COUPLING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/131898
Kind Code:
A1
Abstract:
The present invention realizes a technology that makes it possible to efficiently and inexpensively synthesize an organic magnesium compound simply, in a small number of steps, and without requiring cumbersome chemistry procedures. The present invention is a method for synthesizing an organic magnesium compound that comprises: a step in which, in a reaction solvent, an organic halide represented by general formula I (Ra–Xa) and a dispersion in which sodium is dispersed in a dispersion solvent are made to react to obtain an organic sodium compound represented by general formula II (Ra–Na); and a step in which the obtained organic sodium compound and a magnesium halide represented by general formula III (Mg–(Xb)2) are made to react to obtain an organic magnesium compound represented by general formula IV (Ra–Mg–Xb).
