SPECIFIC COMPOUNDS - 31 Compounds (I) are specifically disclosed e.g. (E)-N-phenyl-6-(4-(phenyl(4-(trimethylsilyl)phenyl)amino)styryl)-N-(4-(trimethylsilyl)phenyl)naphthalen-2-amine of formula (D-1), (E)-4,8-dimethyl-N-phenyl-6-(4-(phenyl(4-(trimethylsilyl)phenyl)amino)styryl)-N-(4-(trimethylsilyl)phenyl)naphthalen-2-amine, (E)-N,N-diphenyl-6-(4-(phenyl(4-(trimethylsilyl)phenyl)amino)styryl)naphthalen-2-amine, (E)-6-(4-(diphenylamino)styryl)-N,4,8-triphenyl-N-(4-(trimethylsilyl)phenyl)naphthalen-2-amine, or (E)-6-(4-(diphenylamino)styryl)-N,N-diphenylnaphthalen-2-amine.    EXAMPLE - The N-phenyl-4-(trimethylsilyl)benzenamine (9 g), (E)-2-bromo-6-(4-chlorostyryl)naphthalene (5.8 g), sodium tert-butoxide (3.25 g), palladium acetate (378 mg), tri-tertbutylphosphine (343 mg) and toluene were put into round bottom flask, and reacted at 90 degrees C for 9 hours. The reaction solution was celite-filtered after cooling. The obtained filtrate was concentrated.
