A tetrahydrofluorene, which is represented by the following formula (I)wherein R1 to R6 each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, or R1 and R2 are combined together to represent =O, =N or =S, R7 and R8 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, a halogen atom, a hydroxyl group or a carboxyl group, is subjected to a hydrogen transfer reaction in the presence of a hydrogen acceptor and a catalyst, whereby a fluorene and a hydride of the hydrogen acceptor are formed at the same time.
