Synthesis of Fluorenes Starting from 2-Iodobiphenyls and CH2Br2 through Palladium-Catalyzed Dual C-C Bond Formation

A facile and efficient approach is developed for the synthesis of fluorene and its derivatives starting from 2-iodobiphenyls and CH2Br2. A range of fluorene derivatives can be synthesized under relatively mild conditions. The reaction proceeds via a tandem palladium-catalyzed dual C-C bond formation sequence through the key dibenzopalladacyclopentadiene intermediates, which are obtained from 2-iodobiphenyls through palladium-catalyzed C-H activation.

Preparation process of fluorenes

A tetrahydrofluorene, which is represented by the following formula (I) wherein R1to R6each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, or R1and R2are combined together to represent ═O, ═N or ═S, R7and R8each 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.
