Yield:-

Reaction Conditions:

with hydrogen fluoride at 20; for 5 h;Inert atmosphere;

Steps:

4.2.4. Reaction of K[(CF3)2CFCCBF3]

B. K[(CF3)2CFCCBF3] (62 mg, 0.21 mmol) was cooled to -40 °C and cold (-40 °C) aHF (0.8 mL) was added. The solution was kept at -15 °C for 20 min and at 0 °C for 1 h (no reaction of K[(CF3)2CFCCBF3]) (11B, 19F NMR). Stirring at ~20 °C for 5 h resulted in the complete hydrodeboration to (CF3)2CFCCH and K[BF4] (ratio 1:1) (11B, 19F NMR).
