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.
一种四氢芴,其由以下式(I)表示
其中R1至R6分别独立地表示氢原子或具有1至4个碳原子的烷基基团,或者R1和R2结合在一起表示═O、═N或═S,R7和R8分别独立地表示氢原子、具有1至4个碳原子的烷基基团、具有1至4个碳原子的烷氧基、卤素原子、羟基或羧基,该四氢芴在氢受体和催化剂存在下进行氢转移反应,从而同时形成芴和氢受体的氢化物。
