Reaction Steps

The fraction was charged in an autoclave, and Pd/C (5% Pd supported on charcoal) was added in a proportion of 1% based on the fraction. The resulting mixture was heated to 250° C., followed by a reaction under spontaneous pressure for 2 hours. After completion of the reaction, the reaction mixture was analyzed by gas chromatography. A mixture of position isomers of methylfluorene was found to have been formed with a yield of 96% (based on methyltetrahydrofluorene), and indane with a yield of 99% (based on indene).
