synthesized by the reaction of hexafluoropropene oxide (HFPO) with alcohol or phenol. In this reaction, although the insertion reaction of difluorocarbene to OH bond and the nucleophilic attack of alcohol or phenol to HFPO were competition, the insertion reaction proceeded predominantly to give fluorinated ether in the case of low nucleophilic alcohol or phenol. In addition, high reaction pressure is advantageous
ROCHF 2型氟化醚是通过六氟环氧丙烷(HFPO)与醇或苯酚反应合成的。在该反应中,尽管二氟卡宾与OH键的插入反应和醇或酚对HFPO的亲核进攻是竞争的,但在低亲核醇或苯酚的情况下,插入反应主要进行以得到氟化醚。另外,在HFPO与(CF 3)2 CHOH或C 6 F 5 OH的反应中,高反应压力有利于氟化醚的选择性。
