Abstract

By means of a simple procedure, we prepared α-acetoxyketones from a variety of enolizable ketones with PhI(OAc)₂ in the presence of acetic acid. The selectivity of the reactions depended on steric hindrance, and some other reactions were observed, such as the formation of N=N or C=C double bonds through an oxidation reaction.

Keywords: Functionalization α to a carbonyl group; α-acetoxyketones; (diacetoxyiodo)benzene; selectivity
