The Homo Favorskii Rearrangement is the rearrangement of β-halo ketones and cyclobutanones, which in ring systems may yield ring contraction.^[1] This rearrangement takes place in the presence of a base, yielding a carboxylic acid derivative corresponding to the nucleophile (most often the base itself). It must be noted that E1cb will occur if α-carbon adjacent to the halogen atom has hydrogens on it.
