Ferrocene, cas is 102-54-5, it is a common heterocyclic compound, the iron-catalyst compound, its synthesis route is as follows.
A mixture of 5.3g (28mmol) ferrocene and 60mL chloroform was placed in a 50mL three-neck flask and kept at-5 to-10C. Afterward, 10.5mL phosphorus oxychloride dissolved in 15mL DMF was added for 1.5h. The resulting reaction mixture was refluxed for 12h. After solvent removal, the product was poured into 100mL ice water and filtered. The filtrate was neutralized to pH 8-9 using NaOH (10%, w/v) and then extracted with ether. The organic layer was washed with water and dried over anhydrous MgSO4. After removal of the solvent, the crimson solid was recrystallized from n-hexane. The purified product (1) weighed 2.3g (79% yield). 1H NMR(CDCl3): delta, 9.95 (s, 1H, HC=O), 4.79-4.80 (d, 2H, Cp-rings), 4.60-4.61(d, 2H, Cp-rings), 4.28(s, 5H, Cp?-rings). MS(ESI), m/z: 215.0 (M+) FT-IR (KBr): upsilon (cm-1) 1681(C=O).
With the rapid development of chemical substances, we look forward to future research findings about 102-54-5
