TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Disclosed): The benzo fluorenyl amine compound (I) is obtained by carrying out amination reaction of secondary amine of formula: HN(-R1)(-R2) and halobenzo fluorene derivative of formula (II) in presence of palladium catalyst and a base.X=chloro, bromo or iodo. SPECIFIC COMPOUNDS - 2 Benzo fluorenyl amine compounds i.e. 17,17-dimethyl-N-(4-phenylphenyl)-N-(4-(4-phenylphenyl)phenyl)tetracyclo(8.7.0.02,7.011,16)heptadeca-1(10),2(7),3,5,8,11(16),12,14-octaen-14-amine of formula (Ia) and N-(17,17-dimethyltetracyclo(8.7.0.02,7.011,16)heptadeca-1(10),2(7),3,5,8,11(16),12,14-octaen-14-yl)-17,17-dimethyl-N-(4-phenylphenyl)tetracyclo(8.7.0.02,7.011,16)heptadeca-1(10),2(7),3,5,8,11(16),12,14-octaen-14-amine are specifically claimed.    EXAMPLE - 5.6 g 9-Chloro-11,11-dimethyl-11H-benzo(a)fluorene, 46 g xylene, 5.1 g 4-amino p-terphenyl and 2.7 g sodium t-butoxide were suspended in nitrogen-substituted reactor. 0.04 g Palladium acetate and 0.12 g tri-tert-butylphosphine were added and cured at 140 degrees C for 15 hours. The reaction liquid was cooled and 24 mL water was added. 140 g Tetrahydrofuran was added, precipitate was dissolved and organic phase was liquid-separated. The obtained liquid was recrystallized by adding 92 g ortho xylene to yellow solid, to obtain 7 g light-yellow solid N-(4-p-terphenyl)-N-(9-(11,11-dimethyl)benzo(a)fluorenyl)amine. The obtained 3.4 g N-(4-p-terphenyl)-N-(9-(11,11-dimethyl)benzo(a)fluorenyl)amine, 68 g xylene, 1.6 g 4-bromo-biphenyl and 0.9 g sodium tert-butoxide were suspended in nitrogen-substituted reactor. 0.04 g palladium acetate and 0.13 g tri-tert-butylphosphine were added and cured at 140 degrees C for 15 hours. The reaction liquid was cooled and 20 mL of water was added. 90 g Tetrahydrofuran was added, precipitate was dissolved and organic phase was liquid-separated. The obtained liquid was recrystallized by adding 43 g o-xylene and the eluate was concentrated using toluene, to obtain 3.5 g dimethyl-N-(4-phenylphenyl)-N-(4-(4-phenylphenyl)phenyl)tetracyclo(8.7.0.02,7.011,16)heptadeca-1(10),2(7),3,5,8,11(16),12,14-octaen-14-amine as light-yellow colored compound with yield of 78%.
