Acylphosphonates are potent acyl anion precursors that generate acyl anion equivalents under the promotion of cyanide anion via phosphonate−phosphate rearrangement. These anions readily react with aldehydes to provide cross-benzoin products. In this way it is possible to synthesize a variety of aromatic−aromatic, aromatic−aliphatic, and aliphatic−aromatic benzoins. Moreover the reaction of benzoylphosphonate
