As a common heterocyclic compound, it belongs to iron-catalyst compound, name is Ferrocene, and cas is 102-54-5, its synthesis route is as follows.
(1) Synthesis of ferrocene formaldehyde: under the protection of the helium gas, in the ice-bath cooling, constant pressure in the funnel 14.6 g (0.2 muM) DMF dimethyl formamide in 10 minutes into the 18.6 g (0.1 muM) ferrocene 75 ml dry chloroform solution; then, 30.6 g (0.2 muM) phosphorus oxychloride in a half-hour in dripped into the reaction bottle, the completion of the dropping, the oil bath temperature to 60 C, heating and stirring 20 hr, the oil bath temperature is still lower than the 60 C; the completion of the reaction, the reaction mixture is poured into ice water, the solid is most unreacted ferrocene, filtering to filter the solid insoluble matter, the filtrate magnesium carbonate powder carefully neutralized, then circulating extraction device repeatedly extraction reaction mixture, all of the extracts combined, water washing, the organic layer using sodium carbonate drying, to remove the solvent to obtain the crude product 18.21 g, dichloromethane is used for – hexane recrystallize to get red brown crystal 15.0 g, yield of 72.4%.
102-54-5, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,102-54-5 ,Ferrocene, other downstream synthetic routes, hurry up and to see
