文摘A series of α-bromoarylethanones were prepared in high yields by a practical and efficient method. The arylethanones were reacted with bromine to give a mixture of α- and α, α-dibromides, which were debrominated with diethylphosphite in the presence of triethylamine to give the desired α-monobromo products.
