Abstract
The problem to be solved by the present invention is to provide a novel method for producing a difluoromethylene compound. This problem is solved by a method for producing a difluoromethylene compound containing a —CF2— moiety, the method comprising step A of mixing: a) a carbonyl compound containing a —C(O)— moiety; b) optionally an amine; c) a fluoride represented by the formula: MF, wherein M represents a Group 1 element of the periodic table; d) a halogenated fluorine compound represented by the formula: XFn, wherein X represents chlorine, bromine, or iodine, and n is a natural number of 1 to 5; and e) sulfur chloride.
