Versuchsvorschrift
A 100 mL Hastelloy shaker tube was loaded with 26.5 g (0.227 mole) chlorosulfuric acid, cooled in liquid nitrogen, evacuated and loaded with 30 g (0.225 mole) of 1,1,3,3,3-pentafluoropropene. The reaction vessel was allowed to warm and kept on a shaker at 40° C. at autogenous pressure for 6 hours. The pressure tube was unloaded, and the reaction mixture was added drop by drop into the flask containing 60 ml of ethanol at −10° C. over a 15 minute period. The reaction mixture was stirred overnight at 20° C. and then was poured into 200 ml of ice water. The organic layer was separated, washed with sodium bicarbonate, water, and dried under MgSO4. Distillation gave 31 g of CF3CH2COOEt (87%), bp 108-109° C.
