The convenient, scaleable synthesis of a novel ⟨-fluorinated bisphosphonicacid, incorporating a tethered acrylamide monomer, [1-fluoro-1-phosphono-7-(prop-2-enamido)heptyl]phosphonic acid (1), is described. The α–fluorine substituent offers the advantage (compared to an α–hydroxy) of compatibility with basic conditions in tetraester intermediates (avoiding phosphonate-phosphate rearrangement) while
