Steps:

Reaction procedure for the synthesis of 2H-acenaphthylen-1-one (3)
In a round bottomed flask the 340 mg of compound 2 (2 mmol) was dissolved in 10 mL diethylether and then cooled to 0 °C. Then the acidic dichromate solution (prepared by mixing 1gm of K₂Cr₂O₇, 0.4 mL H₂SO₄and 4 mL of water) was added drop wise for a period of 10 min. The reaction mixture was stirred for additional 30 min at 0 °C. After completion of the reaction, mixture was diluted with saturated solution of Na₂CO₃ and extracted with ether (20 mL x 3) and the combined organic layer was washed with saturated sodium chloride solution, dried over anhydrous Na₂SO₄, and evaporated. The crude product was then purified by column chromatography using silica gel 60-120 mesh and petroleum ether / ethyl acetate (95:5) as eluent. White solid product was obtained in 97% yield.
