Bromination of trimethylsilylbenzoic acids was examined. Addition of equimolar amount of bromine to the acetic acid solution of o-, m-, and p-(trimethylsilyl)benzoic acid, and heating of this mixture in a sealed tube at 100° for 5, 12, and 13 hours respectively afforded o-, m-, and p-bromobenzoic acids. The ease or difficulty of this bromination by desilylation was found to be proportional to the activity of the ortho, meta, and para positions of the benzoic acid.
