Sulfuryl chloride → HCID 54551947, compound

Participants

Reaction Steps

At 10° C., a solution of 14 g (0.104 mole) of sulfuryl chloride in 50 ml of carbon tetrachloride is dripped into a solution of 22.2 g (0.1 mole) of α-formylethanephosphonic acid diisopropyl ester in 150 ml of carbon tetrachloride. The reaction mixture is stirred for 3 hours at room temperature and the solvent is then distilled off under reduced pressure. The residue is taken up in ether, washed with 5% sodium bicarbonate solution and then with saturated sodium chloride solution, and dried over sodium sulfate. The ether is stripped off under reduced pressure. There is obtained 24 g (93.5% of theory) of α-formyl-α-chloroethanephosphonic acid diisopropyl ester.
