Abstract
3,4-Difluoro-2-methoxyphenol was prepared with Mg,B(OCH3)3 and H2O2 from 3,4-difluoro-2-methoxybromobenzene in -30 ℃.Four ester liquid crystal compounds were synthesized by esterification. The structures of liquid crystal compounds were confirmed by IR,1H NMR,and MS,the phase transition temperature was measured by DSC.
