摘要
在优化条件下,用NaH、n-BuLi、THF、芴、溴、二溴代烃、二酮为原料,通过溴代反应合成了新型的含芴发光材料前体9-(2,7-二溴-9-正丁基-9-H-芴)壬烷-2,4-二酮(DBBFOD);产物的收率为56%,纯度>99%,其结构经1 H NMR、13 C NMR、MS和元素分析确证.
In optimum reaction conditions, an foremolecular substitution reaction of flourene, bromine,dibromoalkane,diketone,NaH and n-BuLi has been carried out in THF. The 9-(2,7-dibromo 9-butyl-9-H-fluorene) nonane-2,4-ketone(DBBFOD) a new type luminescent material intermediate was synthesized for the first time and identified by 1H NMR,13 C NMR, MS techniques and elemental analysis. The product of yield reached 56G and purity was higher than 99%.
