Page/Page column 4; 5, (2014/06/11)
A process to manufacture substituted tetracyano-hexaazatricyclics with the substitutions occurring at the 9 and 10 hydrogens. The process begins with 2,3-dichloro-5,6-dicyanopyrazine, which is reacted to form the desired tetracyano-hexaazatricyclic. Different process embodiments enable different reaction paths to the desired tetracyano-hexaazatricyclic. Different tetracyano-hexaazatricyclic embodiments include bis(2-methoxyethyl)-2,3,6,7-tetracyano-1,4,5,8,9,10-hexazaanthracene and bis(2-methoxyethoxyethyl)-2,3,6,7-tetracyano-1,4,5,8,9,10-hexazaanthracene.

A highly efficient one-pot synthesis of 5,6-disubstituted-5H-pyrrolo[2,3-b] pyrazine-2,3-dicarbonitriles is presented. The reaction of 5-(alkyl-arylamino)- 6-chloropyrazine-2,3-dicarbonitriles with phenylacetylene, catalyzed by Pd-Cu, in the presence of SDS as the surfactant in water, leads to the desired products in good-to-high yields.
