反应机理
碱先拔掉亚磷酸二酯的氢,形成的亚磷酸二酯负离子进攻四氯化碳得到产物。
文献报道还有另外一种机理,利用叔胺做碱时,在反应引发阶段胺并不是拔氢而是先烷基化。【Phosphorus, Sulfur & Silicon and Related Elements, 1993, 83, 157】

Diethyl N-phenylphosphoramide (4). To an ice cold stirred suspension of formylanilide 1 (605 mg,5 mmol) in CCl4 (25 mL) was added 30% NaOH (10 mL) and TEBAB (0.2 g). Diethyl phosphite 2(828 mg, 6 mmol) in CCl4 (5 mL) was added dropwise. After 1 h at 0 ℃ and 4 h at 20 ℃, the organic layer gave 4, after crystallization, 0.687 g (60%), mp 96–97 ℃.

Diethyl phophoramide (5). Into vigorously stirred liquid NH3 (15–20 mL), 1.0 mmol of iodoform and 1.1 equiv of dialkyl phosphite 2 were added simultaneously at 33 C. After 5–10 min of stirring at 33 C, the cooling bath was removed and stirring was continued until NH3 was distilled off. The product was dissolved in dry chloroform and the mixture was filtered through Celite. After evaporation of the solvent, crystallization or distillation afforded 5 (83%).
