Efficiency phosphorescent OLEDs with a low roll-off based on a hetero-triplet iridium complex

In order to explore the triplet-triplet annihilation in cyclometalated iridium complexes, a hetero-triplet iridium complex [Ir(ppy)2pbi] employing two 2-phenylpyridine (Hppy) ligands and one 1,2-diphenyl-1H-benzo[d]-imidazole (Hpbi) ligand with

Access to 2-Arylquinazolin-4(3H)-ones through Intramolecular Oxidative C(sp3)?H/N?H Cross-Coupling Mediated by I2/DMSO

A novel approach for the synthesis of 2-arylquinazolin-4(3H)-ones was developed. A series of title compounds were obtained with good functional group tolerance and good yields by I2/DMSO-mediated intramolecular oxidative cross-coupling of 2-(benzylamino)benzamides to form C=N double bonds. This method was applicable for gram-scale synthesis. A proposed reaction pathway based on some control experiments was also provided.

Ionic-Liquid-Catalyzed Synthesis of Imines, Benzimidazoles, Benzothiazoles, Quinoxalines and Quinolines through C?N, C?S, and C?C Bond Formation

We report the tetramethyl ammonium hydroxide catalyzed oxidative coupling of amines and alcohols for the synthesis of imines under metal-free conditions by utilizing oxygen from air as the terminal oxidant. Under the same conditions, with ortho-phenylene diamines and 2-aminobenzenethiols the corresponding benzimidazoles and benzothiazoles were obtained. Quinoxalines were obtained from ortho-phenylene diamines and 1-phenylethane-1,2-diol, the conditions were then extended to the synthesis of quinoline building blocks by reaction of 2-amino benzyl alcohols either with 1-phenylethan-1-ol or acetophenone derivatives. The formation of C?N, C?S and C?C bonds was achieved under metal-free conditions. A broad range of amines (aromatic, aliphatic, cyclic and heteroaromatic) as well as benzylic alcohols including heteroaryl alcohols reacted smoothly and provided the desired products. The mild reaction conditions, commercially available catalyst, metal-free, good functional-group tolerance, broad range of products (imines, benzimidazoles, benzothiazoles, quinoxalines and quinolines) and applicability at gram scale reactions are the advantages of the present strategy.

SYNTHESIS METHOD OF IMIDAZOLES

PROBLEM TO BE SOLVED: To provide benzimidazoles with small number of processes at high selectivity and high purity. SOLUTION: A synthesis method of benzimidazoles synthesizes at least one of an imidazole derivative and a carboxy imidazole derivative by reacting a diamine derivative and at least one of a dicarboxylic acid derivative and a dicarboxylic acid anhydride derivative in subcritical water or in supercritical water. For example, in subcritical water or in supercritical water, by reacting o-phenylene diamine and at least one of phthalic acid and phthalic anhydride, 2-phenylbenzimidazole and 2-o-benzimidazole benzoate are synthesized.
