N－取代硫代磷酰胺二乙酯合成新方法的研究

Study on the New Method for Synthesis ofN-Substituted-O , O-diethylphosphoramidothioates

以ＰＥＧ作相转移催化剂，在无机碱（Ｋ＿２ＣＯ＿３或Ｎａ＿２ＣＯ＿３）存在下，用乙基氯化物（Ｏ，Ｏ－二乙基硫代磷酰氯）与不同的胺反应，合成了六种Ｎ－取代硫代磷酰胺二乙酯，其结构经ＩＲ、ＮＭＲ和元素分析证实。

N-Substitute-O, O-diethylphosphoramidothioates(I) were prepered by treating O , O-di-ethylphcophorochloridothioate with different amines in the preesence of anhydrous potassium carbonatewith polyethylene glycol as phase transfer catalyst. The chemical structures of the preducts were con-firmed by elementary analysis, IR and NMR spectra.
