반응 단계
Methanol (12.8 gm., 0.4 mol.) and triethylamine (40.4 gm., 0.4 mol.) are dissolved in 750 ml. ether and chilled in an ice bath. Phenyl dichlorophosphine (35.8 gm., 0.2 mol.) is added dropwise and the reaction mixture is stirred overnight. The resulting suspension is filtered and the filtrate concentrated to an oil which is distilled in vacuo to give the product, phenylphosphonous acid dimethyl ester, b.p. 100°-105° /10 mm; yield 20 gm. (59%).
