摘要

Abstract Quantitative free radical addition of perfluoroethyl iodide to propargyl alcohol in the presence of sodium hydrosulfite gave E/Z-2-iodo-4, 4, 5, 5, 5-pentafluoro-2-penten-1-ols, which were converted to 4, 4, 5, 5, 5-pentafluoropentan-1-ol in one step in excellent yield by catalytic hydrogenation over platinum oxide in the presence of triethylamine. 4, 4, 5, 5, 5- Pentafluoropentan-1-thiol was obtained in good yield via modified Mitsunobu reaction of ...
