研究以二茂铁为初始原料,先经过酰基化反应,生成乙酰基二茂铁,然后再进行克莱门森反应还原乙基二茂铁,两部反应在同一反应烧瓶中进行,减少中间提纯、洗涤、蒸馏等操作,反应总体收率在80%以上,该方法操作简单,适宜工业化生成。 Ferrocene as a starting material to study the first acylation reaction to form acetyl ferrocene, and then proceed to Clementine reaction reduction of ethyl ferrocene, the two reactions in the same reaction flask to reduce the intermediate purification , Washing, distillation and other operations, the overall yield of the reaction in more than 80%, the method is simple, suitable for industrial production.
