The reaction of silylketene acetals with acryloyl, methacryloyl and crotonyl chlorides gave, after addition of methanol, mainly substituted glutaric esters, probably via a (2 + 2) cycloaddition.
A light-emitting element including a phosphorescent organometallic complex is provided. The organometallic complex emits phosphorescence in the yellow green to orange wavelength range and has high emission efficiency and high reliability. Thus, the organometallic complex that exhibits phosphorescence is provided. The organometallic complex, in which nitrogen at the 3-position of a pyrimidine ring is coordinated to a metal, a carbazole skeleton is bonded to the 4-position of the pyrimidine ring, and the carbazole skeleton is bonded to the metal, is used as an emission center. The metal is preferably a Group 9 element or a Group 10 element, more preferably iridium.
A light-emitting element includes an EL layer between a pair of electrodes. The EL layer contains a first compound and a second compound. The first compound is a phosphorescent iridium metal complex having a LUMO level of greater than or equal to −3.5 eV and less than or equal to −2.5 eV, and the second compound is an organic compound having a pyrimidine skeleton. The light-emitting element includes an EL layer between a pair of electrodes. The EL layer contains a first compound and a second compound. The first compound is a phosphorescent iridium metal complex having a diazine skeleton, and the second compound is an organic compound having a pyrimidine skeleton.
As a novel substance having a novel skeleton, provided is a novel phosphorescent organometallic iridium complex that can emit phosphorescence in a blue green to red wavelength region and has high emission efficiency. The phosphorescent organometallic iridium complex has a ligand having a pyridyl pyrimidine skeleton, i.e., the phosphorescent organometallic iridium complex has a ligand having a structure represented by the following general formula (G0).
Note that in the formula, R
1
and R
4
to R
6
separately represent hydrogen or an alkyl group having 1 to 6 carbon atoms; and R
2
and R
3
separately represent any of hydrogen, an alkyl group having 1 to 6 carbon atoms, a phenyl group that may have a substituent, and a pyridyl group that may have a substituent.
