Reaction Steps

A solution of 3,3-bis-ethylsulfanyl-1,1,1,2,2-pentafluoro-propane (example C.26 step 1) (125.8 g, 495 mmol) in DCM (495 mL) and 3M KOH (97.97 g KOH (85%) in 495 ML H2O), with a catalytic amount of n-BuN4Br (4.785 g, 3 mol %), was stirred at 23° C. for 3 h. The organic layer was separated and dried over MgSO4. The solvent was removed by cautious rotary evaporation (470 mbar, 40° C., 100 rpm) to give an orange liquid (ca. 145 g, 125%). Vacuum distillation gave the title compound as a colorless liquid (109.82 g, 95%; bp 86–87° C. at 32 mbar). [according to J. Org. Chem. 1993, 58(1), 29–31. MS (GC-MS; EI) 234.1 [(M)+].
