Reaktionsschritte
The process for producing 1-methyl fluorene by the reduction of 1-hydroxymethyl fluorene involves four steps when one uses fluoranthene as the starting material. The first step involves the conversion of the fluoranthene to 1-carboxylic acid fluorenone, preferably by the reaction of the fluoranthene with hydrogen peroxide in acetic acid. The resulting 1-carboxylic acid fluorenone is then reduced with hydrogen using a palladium carbon catalyst in the same manner as previously described. The resulting 1-carboxylic acid fluorene is then reduced using a lithium aluminum hydride/aluminum chloride catalyst to obtain the 1-hydroxymethyl fluorene which is then reduced with hydrogen in the presence of a palladium carbon catalyst.
