Potentiometric study of phenacyl alcohol reveals it to form a 21 complex with calcium in aqueous solution, with a formation constant log 10 beta of 3.93 at 37 deg C. In contrast, magnesium appears not to form any complexes under analogous conditions, while strontium and barium form complexes of both 11 and 21 ligandmetal stoichiometry. The efficiency of complexation of calcium by this simple alpha-hydroxy ketone and its high ability to discriminate between calcium and magnesium are both rather remarkable given the simplicity of its binding site.
