  • Method for producing difluorocyclopropane compound
    Patent number: 8729320
    Abstract: Provided is a method for producing a difluorocyclopropane compound under milder reaction conditions and with high selectivity and high yield. The method for producing a difluorocyclopropane compound of the present invention is characterized by using sodium bromodifluoroacetate as a difluorocyclopropanation agent. With the disclosed method, a difluorocyclopropane compound can be produced under milder reaction conditions and with a higher conversion rate and a higher yield compared to conventional art. Further, by-products can be reduced significantly, thus allowing waste to be greatly reduced. Accordingly, the production method of the present invention is easy to implement industrially (can be employed on an industrial scale) and is thus extremely practical and useful.
