Catalytic aromatic amination is achieved in water under heterogeneous conditions by the use of immobilized palladium complexes coordinated with the amphiphilic polystyrene‐poly(ethylene glycol) resin‐supported di(tert‐butyl)phosphine ligand. Aromatic amination of arylhalides with diphenylamine and N,N‐double arylation of anilines with bromobenzene were found to proceed in water with broad substrate
Novel iron-catalyzed amination reactions of various aryl bromides have been developed for the synthesis of diaryl- and triarylamines. The key to the success of this protocol is the use of in situ generated magnesium amides in the presence of a lithium halide, which dramatically increases the product yield. The present method is simple and free of precious and expensive metals and ligands, thus providing

Catalytic aromatic amination was achieved in water under heterogeneous conditions by the use of palladium complexes anchored to the amphiphilic PS-PEG resin with little palladium leaching to provide a green and clean (metal-uncontaminated) protocol for the preparation of triarylamines, including the optoelectronically active N,N,N',N'-tetraaryl-1,1'-biphenyl-4,4'-diamines (TPDs).

The present invention provides novel anthracene derivatives. In particular, the present invention provides light-emitting elements with high luminous efficiency, and light-emitting elements with long lifetime. Further, the present invention provides light-emitting devices and electronic devices having long lifetime by using these light-emitting elements. An anthracene derivative represented by the general formula (1) is provided. In addition, since the anthracene derivative represented by the general formula (1) has high luminous efficiency, a light-emitting element using the anthracene derivative represented by the general formula (1) can also have high luminous efficiency. By using the anthracene derivative represented by the general formula (1), light-emitting elements with long lifetime can be provided.
