2-丁二酸单乙酯酰基-9,9-双甲氧甲基芴的制备

以芴为主要原料，经过醚化、酯化和Friedel-Crafts酰基化等反应，合成出了9,9-双羟甲基芴、9,9-双甲氧甲基芴、丁二酸单乙酯和丁二酸单乙酯酰氯4种中间体，并最终合成出目的产物2-丁二酸单乙酯酰基-9,9-双甲氧甲基芴。采用核磁共振对中间体和目的产物的结构进行了表征和分析。最后以2-丁二酸单乙酯酰基-9,9-双甲氧甲基芴为内给电子体合成出新型聚丙烯催化剂，采用丙烯液相本体聚合的方法，对催化剂催化丙烯聚合反应的性能进行了评价。

Synthesis of 2-monoethyl succinyl-9,9-bis(methoxymethyl)fluorene

Four intermediate products, 9,9-bis-(hydromethyl)fluorene, 9,9-bis(methomethyl) fluorene, monoethyl succinate and monoethyl succinyl chloride, were synthesized via etherification, esterification and Friedel-Crafts acylation, using fluorene as the starting material. 2-monoethyl succinyl-9,9-bis(methoxymethyl)fluorene was finally synthesized as the end product. The intermediate products and end product were characterized by 1H-NMR and 13C-NMR. A novel propylene polymerization catalyst was synthesized using 2-monoethyl succinyl-9,9- bis(methoxymethyl) fluorene as the internal electron donor and the performance of the catalyst was tested for propylene bulk polymerization.
