A 3-necked round bottom flask fitted with dropping funnel, dry-ice condenser, and gas inlet was charged with 10% Pd/C(0.35 g) and cooled to 0° C. Triisopropylsilane (7.29 g, 46 mmol) was added, and CF3CF2CF2C(O)Cl (9.30 g, 40 mmol) was added dropwise over a 10 min period. The reactor was connected to a cold trap (-78° C.) while the mixture was stirred for 18 hr. Transfer from the trap and reaction vessel gave a total of 5.1 g (62%) of colorless liquid. 1H NMR (CD2Cl2): 9.62 (m). 19F NMR: -81.24 (t, J=8.3 Hz), -126.4 (quartet of doublets, Jq =8.3, Jd =3.2), -127.9 (s).
