Abstract

Irradiation of the acetonitrile solution of 4′-(5, 6-dicyanopyrazin-2-yl) benzo-15-crown-5 (1) or 4-(5, 6-dicyanopyrazin-2-yl)-1, 2-dimethoxybenzene (2) in the presence of triethylamine gave monodecyano-derivative (3 or 4) and bisdecyano-derivative (5 or 6). Sodium ion stimulates the reaction of the crown ether derivative.
