METHOD OF PRODUCING DIFLUOROCYCLOPROPANE COMPOUNDS
Document Type and Number:
Japanese Patent JP2015063491
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of producing difluorocyclopropane compounds efficiently.SOLUTION: According to a method of this invention, a bis (trifluoromethyl) zinc DMPU complex that is represented by (CF)Zn (DMPU)(1) (where DMPU shows N,N'-dimethyl propylene urea) and is stable at room temperature and useful as a reaction reagent, and olefins or acetylenes are reacted with each other, to obtain difluorocyclopropane compounds.
