Abstract
Acetylferrocene was synthesized through acylable reaction of Friedel-Crafts using acetic anhydride as acetylizing agent and phosphor acid as catalyst.Mannich reaction of acetylferrocene gave β-diethylin-propionylferrocene.The influence of the react temperature,mole ratio of the reactants,the reaction time and the quantity of the catalyst on the synthetic technology were investigated,the results indicate that the optimum synthetic technology are:mole ratio of acetylferrocene,formaldehyde and diethyline is 1∶1.8 ∶2.5～1∶1.8∶2.8;the reaction temperature is 50 ℃;the quantity of the catalyst is 1～1.3 mL;the reaction time is 6～6.5 h.Its structure is characterized by MS and IR,yield is 70%.
