二茂铁和乙酰氯在三氯化铝的催化下,在二氯甲烷中发生傅-克反应得到了较高产率的二乙酰基二茂铁(80.5%),考查了反应时间,傅-克反应催化剂、酰化剂的量对反应的影响;再将二乙酰基二茂铁通过卤仿反应得到二茂铁二甲酸,通过紫外光谱法研究了二茂铁、二乙酰基二茂铁、二茂铁二甲酸的光谱性质,其中二乙酰基二茂铁相对二茂铁发生了较明显的红移. Ferrocene and acetyl chloride in aluminum trichloride catalysis, in the methylene chloride Fu-grams reaction to obtain a higher yield of diacetyl ferrocene (80.5%), the reaction time, Fu-grams Reaction catalyst and amount of acylating agent on the reaction. Then, ferrocene dicarboxylic acid was obtained by the reaction of diacetyl ferrocene with haloform, and the reaction of ferrocene, diacetyl ferrocene, The spectroscopic properties of ferrocene dicarboxylic acid, of which diacetyl ferrocene ferrocene relatively obvious red shift.
