[GRAPHICS]The palladium-catalyzed N-(hetero)arylation of a number of heteroarylamines including 2-aminopyridines, 2-aminothiazoles, and their analogues has been realized using Xantphos as the ligand. Weak bases such as CS2CO3, Na2CO3, and K3PO4 were used in most cases to allow for the introduction of functional groups. Choice of the base and solvent was critical for the success of these reactions.

Provided are novel organic electroluminescent compounds and organic electroluminescent devices and organic solar cells comprising the same. Specifically, the organic electroluminescent compounds according to the invention are characterized in that they are represented by Chemical Formula (1):
wherein, R
1
through R
10
cannot be hydrogen all at the same time.
The organic electroluminescent compounds according to the invention exhibit high luminous efficiency and excellent color purity and life property of material, so that an OLED having very good operation life can be manufactured therefrom.
