Indene → Fluorene

Participants

Reaction Steps

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 Pd/C (5% Pd supported on charcoal) was added as a catalyst in a proportion of 3%. As a result of an analysis by gas chromatography, fluorene and indane were found to have been formed with a yield of 96% (based on tetrahydrofluorene) and with a yield of 97% (based on indene), respectively.
