9-(2,7-二溴-9-正丁基-9-H-芴)壬烷-2,4-二酮的合成与表征

摘要

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,13C NMR、 MS techniques and elemental analysis.The product of yield reached 56% and purity was higher than 99%.%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1H NMR、13C NMR、MS和元素分析确证.
