Abstract:
(EN)
The present invention addresses the problem of providing a novel method for manufacturing a difluoromethylene compound. The problem is solved by a method for manufacturing a difluoromethylene compound having a –CF
2
- part, the manufacturing method including a step A for mixing: a) a carbonyl compound having a –C(O)- part, b) an amine as needed, c) a fluoride represented by the formula MF (where M represents a group 1 element in the periodic table), and d) a fluorine halide compound represented by the formula XF
n
(where X is chlorine, bromine, or iodine, and n is a natural number from 1 to 5); and e) sulfur chloride.
(FR)
L’invention a pour objet de fournir un nouveau procédé de fabrication de composé difluorométhylène. Plus précisément, l’invention concerne un procédé de fabrication d’un composé difluorométhylène qui possède une partie -CF
2
-. Ce procédé de fabrication inclut une étape (A) au cours de laquelle sont mélangés a) un composé carbonyle possédant une partie -C(O)-, b) si souhaité, une amine, c) un fluorure représenté par la formule : MF (Dans la formule, M représente un élément du premier groupe du tableau périodique.), d) un composé fluor halogéné représenté par la formule : XF
n
(dans la formule, X représente un chlore, un brome ou une iode, et n représente un entier naturel de 1 à 5.), et e) un chlorure de soufre.
