摘　　要：在-30℃条件下,以3,4-二氟-2-甲氧基溴苯为原料,通过制备格式试剂,并与硼酸三甲酯和过氧化氢反应,合成了中间体3,4-二氟-2-甲氧基苯酚。通过酯化合成了4种侧向甲氧基取代的液晶化合物。目标化合物经IR,1HNMR,MS和元素分析,确认了分子结构。液晶的相变温度通过差热扫描仪测定。3,4-Difluoro-2-methoxyphenol was prepared with Mg, B（OCH3）3 and HzOz 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.
