    摘要: In the preparation of 3-bromo-4-fluorotoluene by reacting 4-fluorotoluene with bromine, the improvement which comprises effecting the bromination in glacial acetic acid in the presence of iodine and iron or an iron salt. As a result the proportion of 3-bromo-4-fluorotoluene relative to its 2-bromo-4-fluorotoluene isomer is markedly increased.
