聚苯乙烯－路易斯酸复合物催化下某些二茂铁衍生物的醚化及缩酮化反应

Etherification and Ketald Formation of Some Ferrocene Derivatives Catalyzed by Polystyrene-Lewis Acid Complex

将易于水解的ＡｌＣｌ＿３和ＴｉＣｌ＿４与交联聚苯乙烯小球（含ＤＶＢ７％，粒度０．３～０．６ｍｍ）制成稳定的复合物，研究了该类载体催化剂存在下二茂铁甲醇的醚化反应及乙酰基二茂铁的缩酮化反应，对产物进行了元素分析、红外光谱及质子核磁共振谱表征．

olystyrene-DVB copolymer beads(DVB.7%0.3～0. 6 mm)is combined with anhydrousAlCl_3 or TiCl_4 in CS_2 to form a stable complex. The etherification of FcCH_2OH(Fc=Ferrocenyl)and ketal formation of FcCOCH_3 with HOCH_2CH_2OH catalyzed by these polymer supported cata-lysts are investigated. IR and HINMR spectra of the compounds are also studied.
