TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Disclosed): Aromatic amine derivative (I) is obtained by performing coupling reaction of aromatic halogenated compound and amine derivative in presence of palladium catalyst. Preferred Compound: The aromatic amine derivative (I) is preferably of formula: B1-CH=CH-X1-N(-X3-CH=CH-B3)-X2-CH=CH-B2 (II), more preferably of formula (III), most preferably of formula (IV).R1,R2=alkyl, aromatic group, fluoro, alkoxy or (un)substituted silyl;andR1+R2=(un)saturated cyclic structure.Preferred Element: The organic electroluminescent element has an organic thin film layer(s) containing a light emitting layer formed between a cathode and an anode. The light emitting layer contains anthracene derivative of formula (V) and aromatic amine derivative (I).Ar11,Ar12=5-50C monocyclic ring or 8-50C condensed ring (both optionally substituted);andR3-R10=5-50C monocyclic ring, 8-50C condensed ring, 1-50C alkyl, 3-50C cycloalkyl, 1-50C alkoxy, 7-50C aralkyl, 6-50C aryloxy (all optionally substituted), silyl, halo, H or cyano. Preferred Definitions:    one of X1,X2=optionally substituted 10-30C fused aromatic ring or 10-30C condensed heterocyclic ring, and remainder is optionally substituted 6-30C non-fused aromatic ring or 6-30C non-condensed heterocyclic ring;    X3=fluorenylene;and    A1=aromatic group or heterocyclyl (both optionally substituted).    SPECIFIC COMPOUNDS - 39 Aromatic amine derivatives (I) e.g. (9,9-Dimethyl-7-((E)-styryl)-9H-fluoren-2-yl)-bis-(4-((E)-styryl)-phenyl)-amine of formula (1A), bis-(9,9-dimethyl-7-((E)-styryl)-9H -fluoren-2-yl)-(4-((E)-styryl)-phenyl)-amine, 6-((E)-styryl)-naphthalen-2-yl)-bis-(4-((E)-styryl)-phenyl)-amine, (4-((E)-2-dibenzofuran-4-yl-vinyl)-phenyl)-(9,9-dimethyl-7-((E)-styryl)-9H-fluoren-2-yl)-(4-((E)-styryl)-phenyl)-amine, and (9,9-Dimethyl-7-((E)-styryl)-9H-fluoren-2-yl)-(4-((E)-2-(9-ethyl-9-methyl-9H-fluoren-2-yl)-vinyl)-phenyl)-(4-((E)-styryl)-phenyl)-amine are disclosed.    EXAMPLE - 7-Bromo-9,9-dimethyl-9H-fluorene-2-carbaldehyde was reacted with benzyl diethyl phosphonate (15.7 g) in presence of tetrahydrofuran (100 ml) and potassium tert-butoxide (9.1 g) to obtain 2-bromo-9,9-dimethyl-7-((E)-2-phenylvinyl)-9H-fluorene. The obtained compound (5.4 g) was reacted with bis-(4-((E)-styryl)-phenyl)-amine (5.3 g) under argon atmosphere in presence of sodium tert-butoxide (2.8 g), palladium acetate (100 mg), tri-tert-butylphosphine (91 mg) and toluene to obtain (9,9-dimethyl-7-((E)-styryl)-9H-fluoren-2-yl)-bis-(4-((E)-styryl)-phenyl)-amine.
