METHOD OF PRODUCING FLUOROPROPYLENE CARBONATE Russian patent published in 2012 - IPC C07D317/42 

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing fluoropropylene carbonate of formula (2): wherein R¹, R², R³ and R⁴ are identical or different and each denotes H or CH₂F; at least one of R¹, R², R³ and R⁴ is -CH₂F, by reacting a fluorinating agent with a propylene carbonate derivative of formula (1) in which X¹, X², X³ and X⁴ are identical or different and each denotes a hydrogen atom or -CH₂Y, where Y is a (-OH) group; at least one of X¹, X², X³ and X⁴ is -CH₂Y; and the fluorinating agent is a compound of a quaternary ammonium cation and a fluoride anion or a compound of formula (CH₃CH₂)₂NCF₂CFHCF₃.

EFFECT: method is safe, has high output and is realised in a single step (one reactor).
