Summary:The present invention relates to a novel process for the synthesis of 9, 9-bis (hydroxymethyl) fluorene. Synthesis from fluorene via hydroxymethylation to 9, 9-bis (hydroxymethyl) fluorene and further via etherification to 9, 9-bis (methoxymethyl) fluorene is known. The 9, 9-bis (methoxymethyl) fluorene is a compound useful as an electron donor for Ziegler-Natta catalysts. The present invention relates to improvements in the synthesis of 9, 9-bis (hydroxymethyl) fluorene leading to reduced amounts of solvent used and easier post-treatment while achieving high yield and purity. 本发明涉及一种用于合成9,9-双(羟甲基)芴的新颖方法。从芴经由羟甲基化到9,9-双(羟甲基)芴并且进一步经由醚化到9,9-双(甲氧基甲基)芴的合成是已知的。9,9-双(甲氧基甲基)芴是用作用于齐格勒-纳塔催化剂的给电子体的化合物。本发明涉及9,9-双(羟甲基)芴的合成的改进，导致所使用溶剂的量减少以及更容易的后处理同时实现高的产率和纯度。
