Participants

Reaction Steps

2,7-Bis(diarylamino)-9,9-bis(diarylaminophenyl)fluorene, a compound of this invention, can be synthesized according to the above synthetic route as follows: A mixture of a 2,7-dinitrofluorenone and an aniline is refluxed in the presence of an acid catalyst to give an intermediate 2,7-dinitro-9,9-bis(aminophenyl)fluorene. The two nitro groups are then converted to two amino groups by a reduction reaction with Fe/NH4Cl. Finally, the reduced intermediate is reacted with aryl halides (Ar—X and Ar′—X, stepwise) in the presence of a catalyst such as palladium to produce the desired product.
