Bis(2,6-dimethylphenyl) Chlorophosphate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2,6-dimethylphenol (1 g, 8.18 mmol) and aluminum trichloride (109 mg, 0.818 mmol, 0.1 eq) were added to a microwave vial. Phosphorus oxychloride (0.375 mL, 4.09 mmol, 0.5 eq) was added, the vial was sealed and subsequently heated in the microwave for 1 h. Reaction progress was monitored by TLC, and the reaction was quenched before going to completion. The reaction mixture was diluted with dicholoromethane, washed with water and brine, dried over MgSO4, and filtered through celite. The filtrate was concentrated under reduced pressure providing an oily residue that was taken directly to the next step without further purification. the vial was sealed subsequently heated in the microwave for 1 h Reaction progress the reaction was quenched The reaction mixture was diluted with dicholoromethane washed with water and brine dried over MgSO4 filtered through celite The filtrate was concentrated under reduced pressure providing an oily residue that was taken directly to the next step without further purification

Conditions: temp:120.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A 1,000-ml four-necked flask provided with a stirring machine, a thermometer, a dropping funnel, and a nitrogen-introducing pipe was mounted with a condenser to which a water scrubber had been connected, and then 2.0 mol (244 g) of 2,6-dimethylphenol, and 0.016 mol (1.5 g) of magnesium chloride were loaded into the resultant reactor. The atmosphere in the reactor was replaced with nitrogen and then its temperature was increased to 120° C. 1.0 Mole (153 g) of phosphorus oxychloride was dropped into the reactor at that temperature over 2 hours. After the completion of the dropping, the temperature was increased to 180° C. over 2 hours. Thus, di(2,6-xylyl)phosphorochloridate was obtained. The temperature in the flask was cooled to 20° C., and then 0.5 mol (55 g) of 1,3-benzenediol and 0.016 mol (1.5 g) of magnesium chloride were loaded into the flask. The temperature was increased to 180° C. over 2 hours and then the mixture was aged for 2 hours. After that, the catalyst was removed by an ordinary method and then the remainder was dried at 140° C. under reduced pressure. Thus, X-1 represented by the following general formula (5) was obtained.
