Abstract
Reaction of 2,3-dichloro-5,6-dicyanopyrazine (1) with amines gave mono -substituted or bis-substituted products (2a-h). Reaction of 1 with th ioacetamide as well as 2,3-bis(N-methylamino)-5,6-dicyanopyrazine (2c) gave 1,4,6,9-tetraaza-2,3,7,8-tetracyanothianthrene (5) or 4,6,9-terr aaza-5,10-dimethyl-5,10-dihydrophenazine (6), respectively. Non-linear optical properties for 2a-h as well as biological activity of 4a were evaluated.
