FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing perfluoroalkyl bromide from triphenylphosphine dibromide, obtained by reacting triphenylphosphine with bromine in acetonitrile at 0 °C, and 1,1,3-H-perfluoroheptanol at temperature of 170–180 °C for 90 minutes.
EFFECT: easy implementation, replacing original toxic raw material, while maintaining high output of end product.
