Diethylcyanomethylphosphonate (279 mg, 1.58 mmol) was dissolved in dry THF (6 mL) at 0oC. Sodium hydride (66 mg, 1.15 mmol) was added and, to the resulting suspension, 5-trifluoromethoxyistain (347 mg, 1.50 mmol) was added slowly. Upon completion of the reaction as shown by TLC analysis, water (10 mL), brine (10 mL) and ethyl acetate (10 mL) were added and the aqueous layer extracted with ethyl acetate (3 x 5 mL) and dried with Na2SO4. The solvent was evaporated in vacuo and the resulting solid was purified by column chromatography (PSp:EtOAc 1:0 to 1:1) to yield a yellow product (31%), 1H NMR (400 MHz, CDCl3): d 6.39 (s, 1H), 6.91 (d, J 8.7, 1H), 7.26-7.31 (m, 1H), 7.84 (br s, 1H), 7.94 (d, J 1.9, 1H); 13C NMR (100 MHz, CDCl3): d 99.8, 111.3, 115.3, 118.9, 120.43 (q, J 258), 120.6, 126.9, 141.3, 142.5, 144.8 (q, J 2.1), 165.9; IR (neat, cm-1): 3254, 2228, 1760, 1728, 1624, 1473, 1245, 1124; HRMS: m/z: [M+Na]+ calcd for C11H5N2O2F3Na, 277.0195; found, 277.0188.
