Procedure

A portion of the 2:1 fraction (by molar ratio) of indene and tetrahydrofluorene obtained in Example 1 was charged in an autoclave, and was then reacted and processed in a similar manner as in Example 1 except that the hydrogen transfer reaction was conducted at 230° C. As a result of an analysis by gas chromatography, fluorene and indane were found to have been formed with a yield of 93% (based on tetrahydrofluorene) and with a yield of 95% (based on indene), respectively.
