A simple and convenient procedure was proposed for the synthesis of 4-aryl-3-bromobutan-2-ones from methyl vinyl ketone and arenediazonium bromides under Meerwein reaction conditions.

Both one-pot and two-step procedures for the synthesis of substituted 2-aminothiazoles and 2-aminoselenazoles are described. Anilines are first converted into arenediazonium bromides, which are then reacted with methyl vinyl ketone or cyclopropyl vinyl ketone in the presence of copper(II) bromide to give 4-aryl-3-bromobutan-2-ones (40–71%) and 3-aryl-2-bromo-1-cyclopropylpropan-1-ones (41–79%), respectively
