Palladium-catalyzed construction of heteroatom-containing π-conjugated systems by intramolecular oxidative C-H/C-H coupling reaction
Saito, Kenta,Chikkade, Prasanna Kumara,Kanai, Motomu,Kuninobu, Yoichiro
, p. 8365 - 8368 (2015)
Synthesis of heteroatom-containing ladder-type π-conjugated molecules was successfully achieved via a palladium-catalyzed intramolecular oxidative C-H/C-H cross-coupling reaction. This reaction provides a variety of π-conjugated molecules bearing heteroatoms, such as nitrogen, oxygen, phosphorus, and sulfur atoms, and a carbonyl group. The π-conjugated molecules were synthesized efficiently, even in gram scale, and larger π-conjugated molecules were also obtained by a double C-H/C-H cross-coupling reaction and successive oxidative cycloaromatization.
Domino N-H/C-H bond activation: Copper-catalyzed synthesis of nitrogen-bridgehead heterocycles using azoles and 1,4-dihalo-1,3-dienes

, p. 228 - 231 (2011)
Copper-catalyzed tandem coupling of 1,4-dihalo-1,3-dienes with azoles via an N-H bond and its adjacent C-H bond activation has been described. The reaction exhibits good regioselectivity when unsymmetrical 1,4-dihalo-1,3-diene is employed. This method provided a novel route to the synthesis of nitrogen-bridgehead azolopyridine derivatives.

Palladium-catalyzed tandem N-H/C-H arylation: Regioselective synthesis of N-heterocycle-fused phenanthridines as versatile blue-emitting luminophores
Yan, Lipeng,Zhao, Dongbing,Lan, Jingbo,Cheng, Yangyang,Guo, Qiang,Li, Xiaoyu,Wu, Ningjie,You, Jingsong
, p. 7966 - 7977 (2013/11/19)
A general and highly regioselective synthetic protocol for structurally diverse N-heteroaryl-fused phenanthridines has been developed. Varieties of fluorescence molecules comprising imidazole-fused, benzoimidazole-fused, indole-fused and pyrrole-fused phenanthridines were obtained by this modular approach, some of which exhibit excellent blue-emitting performance, high quantum yields, long fluorescence lifetimes, interesting electrochemical properties, and thermal stabilities.

Object of the present invention is to provide an organic electroluminescent element having an emissive layer that may be formed by wet process in the fabrication of the organic electroluminescence device with multi-layer structure and has excellent electron-injection property, electron-transfer property, durability and luminescent efficiency and a novel alcohol-soluble organic phosphorescent material that may be preferably applicable to the fabrication of the same. An organic electroluminescent element 1 has a plurality of laminated organic layers 4, 5, 6 sandwiched between anode 3 and cathode 7. A hole transport layer 5 composed of organic compounds insoluble in alcohol solvent and an emissive layer 6 formed by a wet process so that it contacts with the hole transport layer 5 on the side facing with the cathode 7 contains host materials consisting of one or more phosphine oxide derivatives soluble in alcohol solvent and guest materials soluble in alcohol solvent which can be excited electrically to emit light.
