The reaction of equimolar amounts of benzaldehyde, phosphorus trichloride, and acetic anhydride has been shown to involve successive formation of benzylidene diacetate (4) and α-chlorobehzyl acetate (5).By an Arbusov reaction, the latter is converted into the dimer (3), previously recognised as the precursor of α-hydroxybenzylphosphonic acid (1a), the known product of an aqueous work-up.A simple preparation of α-chlorobenzyl acetate (5) is described.
