A process for the preparation of alkyl chloromethylphosphonites, ClCH2P(OR)2 (R = Et, Bu), diethyl β-chloroethylphosphonite, ClCH2CH2P(OEt)2, and their conversion to polyphosphinates with the back-bone structures [CH2PO2R]x and [CH2CH2P(O2R)]x, respectively, by an Arbuzov type reaction is described. Hydrolysis to the corresponding polyphosphinic acids is effected by refluxing the esters with conc.
制备烷基氯甲基亚膦酸酯,ClCH 2 P(OR)2(R = Et,Bu),二乙基β-氯乙基亚膦酸酯,ClCH 2 CH 2 P(OEt)2的方法,以及将其转化为具有骨架结构的多膦酸酯的方法Arbuzov分别表示[CH 2 PO 2 R] x和[CH 2 CH 2 P(O 2 R)] x描述了类型反应。水解成相应的多次膦酸的方法是将酯与浓盐酸回流。HCl长时间保存。结构V的多亚膦酸是极好的Ca离子螯合剂。
