Abstract: Tribromomethylarenes were prepared efficiently, at room temperature, from trifluoromethylarenes with boron tribromide as the
brominating reagent. The present process is applicable to the preparation of various substituted benzotribromide derivatives
from substituted benzotrifluoride compounds. p-Substituted benzotrifluoride compounds were found to be more reactive than o-substituted isomers under the given reaction conditions.
Keywords: trifluoromethylarenes - tribromomethylarenes - tribromomethylation - substitution reaction - boron tribromide
