摘　　要：以2-溴二苯并呋喃、正丁基锂、硼酸三丁酯和稀盐酸为原料,超低温下反应,经酸解得B-2-二苯并呋喃基硼酸,反应总产率85.1%。结果表明,最佳反应温度为-120^-100℃,正丁基锂/四氢呋喃溶液:2-溴二苯并呋喃为1:3 g/mL,滴加硼酸三丁酯温度为-100^-80℃以及溶剂需严格干燥除水等影响产物的主要工艺参数。最终产物使用液相色谱-质谱联用、核磁共振谱以及元素分析结构进行了表征,确定产物为目标化合物B-2-二苯并呋喃基硼酸。Organic light-emitting materials screens were efficient,clean,thin and bright,and were becoming popular in mobile devices. B-2-dibenzofuranyl boronic acid,a novel kind of OLED intermediate,was synthesized from 2-bromodibenzofuran,n-butyllithium and tributyl borate by lithiation and hydrolysis reaction with the total yield of 85. 1%. Results showed that the optimal of experimental conditions were determined,the reaction temperature was- 120 ～- 100 ℃,n-butyllithium THF solution∶ 2-bromodibenzofuran was 1∶ 3 g/mL,the temperature of dropping tributyl borate was- 100 ～- 80 ℃,and the solvents should be strictly dry. After that,LC-MS,NMR and element analysis were used to determine the product structure.
