Reaktionsschritte

C4F9SO2N(CH3)(CH2)11OH was prepared using a procedure similar to that described above for preparing C4F9SO2N(CH3)(CH2)4OH. 175.9 g C4F9SO2NHCH3 and 121.4 g 25% NaOCH3 were reacted to produce a solution of C4F9SO2NNaCH3 in about 100 mL diglyme. This solution was treated with 141 g 11-bromoundecanol (available from Aldrich) and heated at 100° C. for 20 hr to form a heavy precipitate. The reaction was quenched in about 600 mL warm water and the resulting lower layer was stripped at 50° C./0.5 mTorr to leave 269.9 g of C4F9SO2N(CH3)(CH2)11OH, a low-melting solid.
