HCID 27546791,3-Dithiolo-(4,5-b)-quinoxaline-2-ylidene-propanedinitrileYield 69%

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-dichloroquinoxaline and 3.95 g of the di(potassiomercapto)methylenemalononitrile is used. The recovered material is a light tan powder weighing 2.8 g with a calculated overall yield of 69 percent and has a melting point greater than 320° C.
