Ferrocene, cas is 102-54-5, it is a common heterocyclic compound, the iron-catalyst compound, its synthesis route is as follows.
102-54-5, General procedure: A solution of acid chloride (63mmol) in 30ml dry dichloromethane was added to a suspension of anhydrous aluminum chloride (8.41g, 63mmol) in 30ml dry dichloromethane and the mixture was stirred at 5C for 1h under Argon. The solution of aluminum chloride: acid chloride complex was added dropwise over 30min to a solution of ferrocene (11.16g, 60mmol) in 100ml dry dichloromethane at 0C. The reaction mixture was warmed to room temperature and stirred for 16h. A solution of NaBH4 (2.38g, 63mmol) in 25ml diglyme was added dropwise to the purple reaction mixture at-5C. An orange solution was formed and stirred at 0C for 1h. The mixture was then hydrolyzed with addition of 20ml water while maintaining its temperature at less than or equal to 10C. The mixture was allowed to separate by settling and the organic phase was then withdrawn. The aqueous phase was extracted with 3 times 30ml of dichloromethane and then all the organic phases are combined. Combined organic layer was washed with 50ml of brine and then dichloromethane was distilled under atmospheric pressure. The diglyme and the residual ferrocene which was found to be entrained by the diglyme were then distilled at reduced pressure approximately 20mm Hg and a column head temperature of 85-95C. The alkylferrocene derivatives were distilled at a more reduced pressure, less than 5mm Hg.
With the rapid development of chemical substances, we look forward to future research findings about Ferrocene
