Phosphorescent organometallic iridium complex, light-emitting element, light-emitting device, electronic device, and lighting device

A novel phosphorescent organometallic iridium complex is provided in which a coordination position of a ligand with respect to a metal can be controlled in synthesis. A novel phosphorescent organometallic iridium complex is provided which can keep high quantum efficiency and can emit phosphorescence in the blue to green wavelength region. A phosphorescent organometallic iridium complex which includes a structure represented by General Formula (G1) and whose ligand is a 4H-1,2,4-triazole compound which has an unsubstituted phenyl group at the 3-position, a substituted or unsubstituted phenyl group at the 4-position, and a phenyl group at the 5-position. In the phenyl group at the 5-position, an alkyl group is bonded to at least one of the ortho-positions, and the other of the ortho-positions, the meta-positions, and the para-position are substituted or unsubstituted.

Light-Emitting Element, Lighting Device, Light-Emitting Device, and Electronic Device

A light-emitting element includes a first electrode; a first light-emitting layer over the first electrode, containing a first phosphorescent compound and a first host material; a second light-emitting layer over the first light-emitting layer, containing a second phosphorescent compound and a second host material; a third light-emitting layer over the second light-emitting layer, containing a third phosphorescent compound and a third host material; and a second electrode over the third light-emitting layer. Between peaks of emission spectra of the first, second, and third phosphorescent compounds, the peak of the emission spectrum of the second phosphorescent compound is on the longest wavelength side and that of the emission spectrum of the third phosphorescent compound is on the shortest wavelength side. The third host material has higher triplet excitation energy than the first host material and the second host material.

Mild and convenient one-pot synthesis of 1,3,4-oxadiazoles

A mild, general, convenient, and efficient one-pot synthesis of 2-phenyl-5-substituted-1,3,4-oxadiazoles is described. Both (hetero)aryl and alkyl carboxylic acids were efficiently condensed with benzohydrazide in the presence of TBTU to give diacylhydrazine intermediates. The latter underwent a smooth TsCl-mediated cyclodehydration reaction to afford 2-phenyl-5-substituted- 1,3,4-oxadiazoles in good to very good yields.

Direct microwave synthesis of N,N′-diacylhydrazines and boc-protected hydrazides by in situ carbonylations under air

Palladium-catalyzed hydrazidocarbonylations of aryl iodides and bromides were performed by controlled microwave irradiation, employing Mo(CO)6 as a convenient CO source. A fluorous phosphine ligand was succesfully used to recycle the catalytic
