Except ior the use ol t~ roniine oil tlie 2-phenylthio ketone XIV (X= H,. Y= SCsH5), broniination of the ketones XIV to the bronioketones XVII in nearly quantitative yield was carried out elegantly by treatment of the ketones with sodium bromate and hydrobromic acid. In one case a perbromide was isolated and then warmed to complete the halogenation. With the 2-aminoketone XIV (X= H, Y= NHz), it proved best to acetylate the amine group before ...
