The thermally unstable α-fluoroalcohol undecafluorocyclohexanol (c-C6F11OH) was prepared by addition of hydrogen fluoride to the corresponding ketone. c-C6F10(CF3)OH was obtained by protonation of its alkoxide [NMe4]+[C7F13O]-. Decafluorocyclohexane-1,1-diol (c-C6F10(OH)2) was prepared by acidic workup of the corresponding alkoxide [NMe4]+[C6F11O]- with sulfuric acid, which yielded (c-C6F10(OH)2) and fluorosulfonic acid. The structures of c-C6F10(CF3)OH·2H2O and of (c-C6F10(OH)2) were elucidated by single-crystal X-ray and gas-phase electron-diffraction studies.
热不稳定的α-氟代醇全氟环已醇（c-C6F11OH）是通过向相应的酮中添加氟化氢制备的。c-C6F10(CF3)OH 通过其烷氧化物[NMe4]+[C7F13O]-的质子化获得。通过用硫酸对相应的烷氧化物[NMe4]+[C6F11O]-进行酸性处理，制备了十氟环己烷-1,1-二醇（c-C6F10(OH)2），得到（c-C6F10(OH)2）和氟硫酸。通过单晶 X 射线和气相电子衍射研究阐明了 c-C6F10(CF3)OH·2H2O 和（c-C6F10(OH)2）的结构。
