POLYFLUOROALKYLPHOSPHONIC ACID ESTERS AND PROCESSES FOR PRODUCTION OF SAME

摘要

Polyfluoroalkylphosphonic acid esters represented by the general formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cP(O)(OR)2 (wherein R is C1-4 alkyl; n is 1 to 6; a is 1 to 4; b is 1 to 3; and c is 1 to 3) can be produced by either 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 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.
