Hydrogen-assisted dehydrochlorination of 1,1,1,2-tetrafluoro-2-chloropropane to 2,3,3,3-tetrafluoropropene over Pd-Ag/nano-MgF2 with optimized Pd isolated sites

Communications Chemistry
Hydrogen-assisted dehydrochlorination process (HaDHC) is an attractive route for the production of fluorine-containing olefins under relatively mild conditions, so far lacking the highly efficient metal-based catalysts and their design strategy. Here, we

Fluorination with Complex Fluorine Compounds

The Journal of the Society of Chemical Industry, Japan, 1969
鉄,アルミニウム,アンチモン,ケイ素,チタンなどの6配位錯フッ化物によるハロゲン交換フッ素化反応について研究した。フッ素化の対象としては,四塩化炭素,クロロホルム,ヘキサクロルエタンなどの有機塩素化合物をえらび,オートクレープ中で250ないし350℃で2時間ないし4時間反応させた。この結果,鉄,アンチモン,アルミニウムなどの錯フッ化勃の活性が大きく,ケイ素の錯フッ化物の活性はこれらについだ。これに対し,チタソの錯フッ化物は不活性であることがわかった。鉄,アンチモン,アルミニウムの錯フッ化物の活性が大きいことは,これら錯フッ化物がリガンド交換活性な外軌道または高スピン錯塩であることによるものと考えられる。実際に,反応後の固体をX線回折分析により調べたところ,低配位錯塩NaAIF4 ...
