Abstract
Abstract Trimethyl phosphite attacks the carbonyl oxygen of aromatic α-ketophosphonates in the presence of proton donors such as carboxylic acids. The intermediate quasi-phosphonium salts (6) either demethylate to a diphosphorus compound (4) in the normal Arbusov manner or dealkylate to give a phosphonate (5) and trimethyl phosphate.
