الإجراء التجريبي

More specifically, a symmetrical compound can be synthesized by the following method: A mixture containing a fluorenone and an aniline is refluxed in the presence of an acid catalyst to produce an intermediate 9,9-bis(aminophenyl)fluorene. The intermediate is subsequently reacted with aryl halides (Ar—X and Ar′—X, stepwise) in the presence of a catalyst such as palladium to obtain the desired symmetrical product. An asymmetrical compound, on the other hand, can be synthesized as follows: A reaction mixture containing a fluorenone and two different anilines (e.g., an aniline and a 2-fluoroaniline as shown in the above scheme) is refluxed in the presence an acid catalyst to produce a mixture including an asymmetric fluorene intermediate. The asymmetric fluorene intermediate is then reacted with aryl halides (Ar—X and Ar′—X, stepwise) in the presence of a catalyst such as palladium to produce the desired asymmetrical product.
