A thiophile-promoted one-potsynthesis of trisubstituted 1,3,5-triazines starting from isothiocyanates, N,N-diethylamidines, and carbamidines has been studied. The reaction proceeds through the formation of intermediary amidinothioureas, which react with carbamidines in the presence of mercury(II) chloride to generate the desired 1,3,5-triazines in good to moderate yields (40–70%).
An iridium complex compound represented by formula (5). Provided is an iridium complex compound that is useful as a material for a light-emitting layer of an organic electroluminescent element, has a narrow half-width of the emission spectrum thereof, has high solubility in a solvent, and has a short wavelength that is not too long and is suitable as a red-light-emitting material.
where in formula (5), Ir represents an iridium atom. X represents a bidentate ligand. m represents an integer of 1 to 3. R
1
to R
