Dimethyl P-phenylphosphonate Use and Manufacturing
General procedure: To a solution of 1 (0.2 mmol) in 2 mL of CH3CN/H2O(v/v = 100/1) was added Selectfluor (71 mg, 0.2 mmol). The mixture was stirred at room temperature for 5-60minutes. After removal of the solvent, the residue was then purified by flash column chromatography on silica gel with petroleum ether/ethyl acetate to give the desired product 2.Molecular ratio, phenylphosphonyl dichloride: methanol: NaOH = 1:5:2 30 grams of phenylphosphonyl dichloride 11 was placed in a four-neck reaction flask, the calculated amount of methanol was added slowly, the temperature was controlled at 20~40 °C, the calculated amount of 30percent NaOH lye was added dropwise, and the reaction was stirred for 2 to 4 hours, 100 grams of water was added to wash with NaCl and methanol, layered, of phenylphosphonic acid diester 7, yield was 90percent and the content was 90percent.
