Abstract

$\alpha$-Bromo-$\omega$-fluoroalkanes are synthesized in 19∼55% yields from the reactions of dibromoalkanes with AgF and TBABr in acetonitrile at $82^{\circ}C$ for 20 minutes. The reaction is monitored with gas-chromatography. 1^H$ NMR and $19^F$ NMR-Spectrometer are used for identification of $\alpha$-Bromo-$\omega$-fluoroalkanes, difluoroalkane, fluoroalken and bromoalkene.

디브로모알칸, AgF 및 tetrabutylammoniumbromide(TBABr)를 acetonitrile 용매하에서 $82^{\circ}C$에서 20분간 반응시켜 19~55%의 수율로 $\alpha$-브로모-$\omega$-플르오르알칸을 합성하였다. 반응 조건은 가스 크로마토그라피를 이용하여 조절하였으며, 반응 생성물인 $\alpha$-브로모-$\omega$-플르오르알칸, 디플르오로알칸, 플르오로알켄 및 브로모알켄을 1^H$ NMR 및 $19^F$ NMR로 확인하였다.
