1,2,4,5-Tetrafluorobenzene
C6H2F4
CAS No.: 327-54-8
It is a very stable material that is impervious to most common chemical reactions, including reduction, oxidation, and base-acid interactions.
The molecule's high reactivity toward electrophiles and nucleophiles makes it an excellent choice for a reaction with other organic compounds. It can also be utilized in fluorine substitution procedures, such as the one that converts aromatic compounds into fluorinated derivatives, due to its fluorination.
Application
1,2,4,5-Tetrafluorobenzene is mostly used as a building block in chemical synthesis. It is particularly useful when generating aromatic compounds with high fluorination levels, such as polyfluoroarenes.
The industrial uses of polyfluoroarenes include organic solar cells, liquid crystals, and electronics. Furthermore, 1,2,4,5-tetrafluorobenzene is used in the production of pharmaceuticals and agrochemicals, where its remarkable stability and reactivity are advantageous properties.
The main synthesis methods of 1,2,4,5-tetrafluorobenzene:
1. J.Am.Chem.Soc., Vol.118, No.7, 1996 reported that perfluorocyclohexane was used as raw material in the presence of zirconocene metal catalyst ((Cp2ZrCl2+Mg/HgCl2) Removal reaction to prepare a straight line of 1,2,4,5-tetrafluoro.
The yield of this method is 35%, the raw materials are not easy, and a precious metal catalyst is used.
2. Hexafluorobenzene or pentafluorobenzene was utilized as a raw material to remove fluorine in the presence of reagents containing phosphorus to generate 1,2,4,5- Tetrafluorobenzene method, according to J.Am.Chem.Soc., 2014, 136, 4634–4639.
Although this process yields roughly 98% of the sample, the catalyst preparation is challenging and the raw components are costly.
