摘要
丁酸酐和三氟化硼配合物在二氯甲烷中与双二茂铁基甲烷、2,2-双二茂铁基丙烷、2,2-双二茂铁基丁烷、2,2-双二茂铁基戊烷进行丁酰化反应所得产物,经中性氧化铝柱层析分离提纯,得10种单酰基和二酰基双二茂铁基烷。对这些新化合物进行了元素分析、红外和核磁波谱鉴定。
In this paper,the authors report butanoyla-tion reactions of some bisferrocenylalkanes.Thebutanoylation of bisferrocenyl methane,2,2-bisferrocenyl propane,2,2-bisferrocenyl butane and2,2-bisferroeenyl pentane was carried out by meansof butyric anhydride and boron trifluoride com-plex in methylene chloride.The products ofacylation reactions were isolated by columnchromatography with neutral aluminum oxide.Amixture of ether-benzene(1:15;V/V)was usedas eluent,ten mono-and di-acylated bisferro-cenylalkanes were obtained.All of these com-pounds are new compounds.This elemental anal-yses were made and their IR,~1HNMR spectrawere characterized.
