Reaction Steps
A 90% yield of 4-hydroxymethyl-2,3,4,5-tetrafluorobenzyl bromide obtained from 1,4-bis(hydroxymethyl)-2,3,4,5-tetrafluorobenzene by treatment with 48% hydrobromic acid was reported by Costello and Milner in Synthetic Communications, 17, 219-221 (1987). However, it has since been shown that treatment of benzenedimethanols lacking nuclear halogen substituents shows no particular selectivity, and accordingly, the unusually high yield in this isolated example is believed to be an anomaly due to insolubility of the monohalogenated product in the reaction media.
