Abstract

FIELD: chemical technology. SUBSTANCE: invention relates to organohaloid compounds. The parent mixture is brominated and fluorinated with a mixture of antimony pentafluoride and bromine at 20-50 C at molar ratio of perfluoroxylenes : SbF: Br= 1:(2-3):(2-3), respectively. Synthesized dibromoperfluoro-1,3-dimethylcyclohexenes were isolated by distillation and dehalogenated. EFFECT: simplified method. 1 tbl
