FIELD: chemistry.
SUBSTANCE: invention relates to three variants of a method for producing a perfluorocycloalkene compound represented by the formula (1), wherein R1-R4 are the same or different and constitute a fluorine atom or a perfluoroalkyl group. According to one variant, the method herein includes conducting a cyclisation reaction of a perfluoroalkadiene compound in the presence of a catalyst, wherein the perfluoroalkadiene compound is represented by the formula (2): wherein R1-R4 are the same or different and constitute a fluorine atom or a perfluoroalkyl group, wherein the catalyst constitutes a fluoride containing at least one metal element from groups 1 to 12 of the Periodic Table of Elements. Invention also relates to a method for producing a perfluoroalkene compound represented by the formula (3), wherein R1-R4 are the same or different and constitute a fluorine atom or a perfluoroalkyl group. CR12R2-C≡C-CR3R42 (3), CR12=CR2-CR3=CR42 (2).
EFFECT: creation of a new perfluorocycloalkene compound.
