Method of synthesizing pyrazine derivative, and light-emitting element, light-emitting device, electronic device, and lighting device |
摘要 |
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. |

1. A method comprising the step of cyclizing an α-diketone and a 1-(haloaryl)ethane-1,2-diamine derivative to form a 2-(haloaryl)pyrazine derivative,
wherein the α-diketone is any one of glyoxal, 1-phenyl glyoxal, benzil, and 9,10-phenanthrenequinone in which phenyl groups of benzil are bonded to each other at the ortho position, wherein the 1-(haloaryl)ethane-1,2-diamine derivative is represented by a formula (A1), wherein α represents an aryl group, wherein X represents halogen, and wherein n is any of 1 to 3. |
