A polyfluoroalkylphosphonic acid ester represented by the general formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cP(O)(OR)2 (R is an alkyl group having 1 to 4 carbon atoms, n is an integer of 1 to 6, a is an integer of 1 to 4, b is an integer of 1 to 3, and c is an integer of 1 to 3) is produced by a process of reacting a polyfluoroalkyl iodide represented by the general formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cI with a trialkyl phosphite represented by the general formula: P(OR)3 or by a process of reacting a polyfluoro-1-alkene represented by the general formula: CnF2n+1(CH2CF2)a(CF2CF2)bCH=CH2 with a dialkyl phosphite represented by the general formula: (RO)2P(O)H.
由通式表示的多氟烷基膦酸酯:CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cP(O)(OR)2(R 是具有 1 至 4 个碳原子的烷基,n 是 1 至 6 的整数,a 是 1 至 4 的整数,b 是 1 至 3 的整数,c 是 1 至 3 的整数)是由通式为CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cI与通式如下的三烷基亚磷酸酯反应制得:P(OR)3或通式如下的多氟-1-烯与通式如下的三烷基亚磷酸酯反应的过程CnF2n+1(CH2CF2)a(CF2CF2)bCH=CH2 与通式为(RO)2P(O)H.
