Versuchsvorschrift

Hexafluoro-2-butyne (21.0 g, 0.13 mol) was transferred into a reaction bottle and 2-methylfuran (12.86 g, 0.157 mol) was added. This resulting mixture bottle was sealed and heated for 15 hr. at 120° C. After cooling, the excess 2-methylfuran was rotoevaporated in vacuo at rt, to give crude title product (29 g, 92%), which was used directly.
