HCID 197708386-Chloro-1,3-dithiolo-(4,5-b)-quinoxaline-2-ylidene-propanedinitrileYield 78%

Procedure

The process of Example 13 is followed except that the 2,3-dichloro-6-nitroquinoxaline is replaced by 3.0 g of 2,3,6-trichloroquinoxaline and 3.5 g of the di(potassiomercapto)methylenemalononitrile is used. The recovered material is a dark brown powder weighing 3.0 g with a calculated yield of 78 percent and has a melting point greater than 300° C.
