摘要：

The reaction of 2,3-dichloro-5,6-dicyanopyrazine (1) with enamines as well as a few tertiary amines as enamine precursors was investigated. Both reactions gave aminovinyl-substituted pyrazine derivatives. During the attempted purification of 3c or 3d by column chromatography on silica gel, 2-chloro-5,6-dicyano-3-(1'-oxocyclopent-2'-yl)pyrazine (4) was obtained, apparently by hydrolytic cleavage. The products prepared are all of interest as potential pesticides.
