Procedure

A mixture of 5.0g (0.016 mole) of 2,7-bis(chloroacetyl)fluorene, 6.3g (0.020 mole) of sodium dichromate and 125 ml of glacial acetic acid was refluxed with stirring for seventeen hours. The resulting precipitate was filtered while the solution was hot, then washed with acetic acid and dried in vacuo to yield the desired product.
