TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): Preparation of (I) comprises either reacting a fluorine derivative containing a leaving group with an amine compound of formula (Ar2-NH-Ar1) (III) using a single-stage Buchwald coupling, or reacting a fluorine derivative containing a leaving group with an amine compound of formula (Ar2-NH2) (IV) and (H2N-Ar1) (V) using a second-stage Buchwald coupling. Preferred Method: The method comprises (a) adding an organometallic compound to the benzochromen-6-one, (b) then performing an acid catalyzed cyclization of 4-hydroxy-fluoro derivative, (c) subsequently performing a conversion of the hydroxy group in position 4 of the fluorene in the leaving group, and (d) subsequently converting fluorene into the desired product. Preferred Components: (I) contain a monoamine compound, and is produced from benzochromen-6-one. Preferred Definitions:    B1a = phenylene, biphenylene, terphenylene, naphthylene, pyridinylene, pyrimidinylene, pyrazinylene, pyridazinylene, triazinylene, dibenzofuranylene, or dibenzothiophene.    SPECIFIC COMPOUNDS - 141 Compounds (I) are disclosed, e.g. 9,9-diphenyl-N,N-bis(4-phenylphenyl)fluoren-4-amine compound of formula (Ia), 9,9-diphenyl-N-(2-phenylphenyl)-N-(4-phenylphenyl)fluoren-4-amine, 9,9-diphenyl-N-(3-phenylphenyl)-N-(4-phenylphenyl)fluoren-4-amine, 9,9-diphenyl-N-(4-phenylphenyl)-N-(4-(3-phenylphenyl)phenyl)fluoren-4-amine, and 9,9-diphenyl-N-(4-phenylphenyl)-N-(4-(3-(3-phenylphenyl)phenyl)phenyl)fluoren-4-amine.    EXAMPLE - 37 g of 2,2-Dibromo-biphenyl was dissolved in 300 ml of dried tetrahydrofuran in a flask. The reaction mixture was heated and then cooled to -78 degrees C. Solution of n-butyllithium (75 ml) in hexane was slowly added dropwise to the reaction mixture for 1 hour. The mixture was stirred for 1 hour at -70 degrees C. Then, benzophenone (21.8 g) dissolved in 100 ml of tetrahydrofuran was added to the mixture at -70 degrees C. After completion of addition, the reaction mixture was slowly warmed to room temperature and quenched with ammonium chloride and then concentrated in a rotary evaporator. The solution was carefully mixed with 510 ml of acetic acid and 100 ml of fuming hydrochloric acid. The mixture was further heated to 75 degrees C and maintained at the temperature for 4 hours to obtain a white solid. The mixture was then cooled to room temperature. The precipitated white solid was suction filtered and washed with methanol. The residue was dried in vacuum at 40 degrees C and worked up to give bis-biphenyl-4-yl-(9,9-diphenyl-9H-fluoren-4-yl)-amine.
