Ｏ，Ｏ二烷基硫代磷（膦）酸衍生物与二甲胺水溶液发生去烷基反应后，生成的硫代磷（膦）酸铵盐与三氯氧磷发生氯化反应，得到硫（酮）代磷（膦）酰氯．本文还讨论了该反应可能的机理
O, O dialkyl thiophosphoric (phosphine) acid derivative and aqueous solution of dimethyl amine dealkylation reaction, the generated phosphorothioate (phosphine) ammonium salt and phosphorus oxychloride chlorination reaction, get Thi (keto) phosphoro (phosphine) acid chloride. This article also discusses the possible mechanism of this reaction
