1,2,4,5-Tetrafluorobenzene
C6H2F4
CAS Nr.: 327-54-8
Nws yog ib yam khoom ruaj khov heev uas yog impervious rau feem ntau cov tshuaj tiv thaiv, nrog rau kev txo qis, oxidation, thiab base-acid kev cuam tshuam.
Lub molecule lub siab reactivity rau electrophiles thiab nucleophiles ua rau nws yog ib qho kev xaiv zoo heev rau cov tshuaj tiv thaiv nrog lwm cov organic tebchaw. Nws kuj tseem tuaj yeem siv rau hauv cov txheej txheem fluorine hloov pauv, xws li ib qho uas hloov cov tshuaj tsw qab rau hauv cov tshuaj fluorinated, vim nws cov fluorination.
Daim ntawv thov
1,2,4,5-Tetrafluorobenzene feem ntau yog siv los ua lub tsev thaiv hauv cov tshuaj synthesis. Nws yog qhov tshwj xeeb tshaj yog thaum tsim cov tshuaj tsw qab nrog cov fluorination siab, xws li polyfluoroarenes.
Cov kev lag luam siv ntawm polyfluoroarenes muaj xws li cov organic solar cells, kua muaju, thiab electronics. Tsis tas li ntawd, 1,2,4,5-tetrafluorobenzene yog siv nyob rau hauv kev tsim tshuaj thiab agrochemicals, qhov twg nws zoo kawg li stability thiab reactivity yog cov khoom zoo.
Lub ntsiab synthesis txoj kev ntawm 1,2,4,5-tetrafluorobenzene:
1. J.Am.Chem.Soc., Vol.118, No.7, 1996 qhia tias perfluorocyclohexane yog siv los ua raw khoom nyob rau hauv lub xub ntiag ntawm zirconocene hlau catalyst ((Cp2ZrCl2+Mg/HgCl2) Tshem tawm cov tshuaj tiv thaiv rau npaj ib txoj kab ncaj nraim ntawm 1,2,4,{10}}tetrafluoro.
Cov txiaj ntsig ntawm txoj kev no yog 35%, cov khoom siv raw tsis yooj yim, thiab siv cov khoom siv hlau muaj txiaj ntsig.
2. Hexafluorobenzene los yog pentafluorobenzene yog siv los ua raw khoom los tshem tawm cov fluorine nyob rau hauv lub xub ntiag ntawm reagents uas muaj phosphorus los tsim 1,2,4,5- Tetrafluorobenzene txoj kev, raws li J.Am.Chem.Soc., 2014, 136, 4634–4639, ib.
Txawm hais tias cov txheej txheem no ua rau kwv yees li 98% ntawm cov qauv, qhov kev npaj catalyst nyuaj thiab cov khoom nyoos yog kim.
