- 5,6-Dichloropyrazine-2,3-Dicarbonitrile
5,6-Dichloro-2,3-dicyanopyrazine is a copper complex that has been shown to be a nucleophilic and reactive agent. It reacts with electron-rich groups such as carboxylates and phenoxy groups in the presence of MgCl2 to give the corresponding 5,6-dichloro-2,3-dicyanopyridines. The magnesium ion coordinates with the nitrogen atom in the central ring to form an octahedral complex. 5,6-Dichloro-2,3-dicyanopyrazine is used as a reagent for coupling reactions because it can react with primary amines and amines by nucleophilic substitution. It also fluoresces when exposed to ultraviolet light. 5,6-Dichloro-2,3-dicyanopyrazine was prepared by reacting 3-(5,6-dichloroimino)p
