102-54-5, Ferrocene is a iron-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
102-54-5, Weigh 5.59g (30mmol) ferrocene was added to 250mL two-necked flask, and then weighed 24mL (254mmol) of acetic anhydride was added to the flask, and then weighed 7mL (including H3PO4 121mmol) 85% phosphoric acid was added slowly to the flask.Temperature was raised to 75 ~ 80C for about 10min, then the flask was immediately cooled in an ice bath, was added to the flask to about 30mL of ice water.After a short cooling with 25% NaOH solution to neutral, a large tan solid precipitated, cooling was continued for some time and the filter cake was washed with an amount of ice water, dry.The crude product is purified by column chromatography (dichloromethane / petroleum ether (60-90) eluting the solvent was evaporated to give an orange solid ferrocene ethyl ketone product 5.30g, yield 77.1% (ferrocene meter ), melting point 83 ~ 85C.
As the paragraph descriping shows that 102-54-5 is playing an increasingly important role.
