- Method of synthesizing pyrazine derivative, and light-emitting element, light-emitting device, electronic device, and lighting device
-
A novel method includes a synthetic pathway in which α-diketone and a 1-(haloaryl)ethane-1,2-diamine derivative are cyclized to each other to form a 2-(haloaryl)pyrazine derivative. Further, a 2-arylpyrazine derivative having an aryl group or a heteroaryl group as a substituent is synthesized by coupling the 2-(haloaryl)pyrazine derivative obtained by the above synthetic pathway and an arylboronic acid or a heteroarylboronic acid. The 2-arylpyrazine derivative obtained by the novel method is useful for a light-emitting element, a light-emitting device, an electronic device, or a lighting device with high emission efficiency.
