Methyl 2,3,3,3-tetrafluoro-2-[1,1,2,3,3,3-hexafluoro-2-(heptafluoropropoxy)propoxy]propanoate → 1H,1H-2,5-Bis(trifluoromethyl)-3,6-dioxa-perfluorononanol

Reaction Steps

CF3CF2CF2OCF(CF3)CF2OCF(CF3)COF obtained in Example 2-6 is reacted with methanol in an equimolar amount in the presence of sodium fluoride to obtain CF3CF2CF2OCF(CF3)CF2OCF(CF3)COOCH3. The obtained CF3CF2CF2OCF(CF3)CF2OCF(CF3)COOCH3 is reacted with sodium borohydride in 2-propanol to obtain CF3CF2CF2OCF(CF3)CF2OCF(CF3)CH2OH. The obtained CF3CF2CF2OCF(CF3)CF2OCF(CF3)CH2OH is employed as the compound in Example 2-1 to carry out the same reaction. Further, the same reactions as in Examples 2-2 to 2-6 are carried out to obtain FSO2CF2CF2COF and CF3CF2CF2OCF(CF3)CF2OCF(CF3)COF.
