General Procedure for the Synthesis of Ortho-bromoarylphosphineOxide General procedure: To a stirred solution of o-bromoiodobenzene (1.3 ml, 10 mmol) in THF (10 ml) wasadded dropwise a solution of i-propylmagnesium chloride (2.0 M in THF, 5 ml, 10mmol) at -40 °C. After 1 h, PCl3 (0.9 mL, 10 mmol) was added and stirred for 40 minat the same temperature. The mixture was then allowed to stand at room temperaturefor 12 h and cooled at -40 °C again. A solution of proper arylmagnesium bromide (1.0M in THF, 22 ml, 22 mmol) was added dropwise. After 1 h, the resulting mixture wasthen stirred at room temperature overnight. Saturated aqueous solution of ammoniumchloride was added and the reaction mixture was extracted with Et2O three times. Thecombined organic layer was washed with water and brine and dried over magnesiumsulfate. The solvent was then evaporated in vacuo and the residue was purified bysilica gel column chromatography with hexane as eluent to afford the correspondingphosphines. After oxidation by H2O2 in acetone, the crude products were purified byusing flash chromatography with ethyl acetate as eluent, giving the pure products.Compounds 1d, 1e, 1f, 1l has been reported in our previous work. |
