Reaction Conditions

Reaction Steps

8.01 g of lauric acid was added to 100 ml of 85% phosphoric acid and 100 g of polyphosphoric acid, and heated at 180° C. for three hours while the pressure was reduced (1 mmHg) with the use of vacuum pump. After the mixture was cooled, 1.86 g of ferrocene and 20 ml of methylene chloride were added, and the resulting mixture was heat-refluxed at 50° C. for 9 hours. Then, the mixture was poured into water, and made to be basic with potassium hydroxide, and subjected to extraction with methylene chloride, and dried. The unreacted ferrocene was removed by a column chromatography, to obtain 3.20 g of undecanylferrocenyl ketone represented by the formula (A) in a yield of 87.0%. The proton nuclear magnetic resonance (1H--NMR) spectrum of the product is shown in FIG. 1.
