摘要：
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.
