実験手順
One hundred and thirty parts of trimethyl phosphite are heated to 125° C. and treated with 100 parts of methyl chloroformate at a rate sufficient to maintain a reaction temperature of at least 100° C. After gas evolution stops, the residue is distilled to obtain 131 parts of dimethyl methoxycarbonylphosphonate, b.p. 83°-85° C./1.2 mm., nD25 = 1.4210.
