    Abstract: Provided is a 5,6-diaryl-2-pyrazyl triflate, its synthetic method, and a method for synthesizing an organometallic complex having a triarylpyrazine ligand from the 5,6-diaryl-2-pyrazyl triflate. The triflate is readily obtained from the corresponding 5,6-diarylpyrazin-2-ol, and the palladium-catalyzed coupling of the 5,6-diaryl-2-pyrazyl triflate with an arylboronic acid derivative leads to a high yield of a triarylpyrazine derivative having high purity. The use of the triarylpyrazine derivative in the reaction with a metal compound such as a metal chloride results in an ortho-metallated organometallic complex with high purity. The high purity of the organometallic complex contributes to the extremely high durability of a light-emitting element.

    Abstract: As a novel substance having a novel skeleton, an organometallic complex having high emission efficiency and improved color purity is provided. The color purity is improved by reducing the half width of an emission spectrum. The organometallic complex is represented by General Formula (G1). In General Formula (G1), at least one of R1 to R4 represents a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms, and the others each independently represent hydrogen or a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms. Note that the case where all of R1 to R4 represent alkyl groups each having 1 carbon atom is excluded. Further, R5 to R9 each independently represent hydrogen or a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms.

    Abstract: An object is to provide a novel organometallic complex. Another object is to provide an organometallic complex that can exhibit yellow to blue phosphorescence. A platinum complex with a tetracoordinate ligand including a phenothiazine skeleton or a phenoxazine skeleton is provided. In the ligand, nitrogen at the 10-position and carbon at the 2-position of the phenothiazine skeleton or the phenoxazine skeleton have a pyridyl group and a phenoxy group, respectively. A five-membered heteroaromatic residue is present at the 3-position of the phenoxy group. The five-membered heteroaromatic residue has two or three nitrogen atoms in its skeleton. Carbon at the 1-position of the phenothiazine skeleton or the phenoxazine skeleton and carbon at the 2-position of the phenoxy group are bonded to platinum, and nitrogen of the pyridyl group and nitrogen or carbene carbon of the five-membered heteroaromatic residue are coordinated to platinum.
