HCID 197708166-Trifluoromethyl-1,3-dithiolo-(4,5-b)-quinoxaline-2-ylidene-propanedinitrileYield 88%

Procedure

The process of Example 13 is followed except that the 2,3-dichloro-6-nitroquinoxaline is replaced by 0.50 g of 2,3-dichloro-6-trifluoromethylquinoxaline and 0.49 g of the di(potassiomercapto)methylenemalononitrile is used. The recovered material is a dark yellow powder weighing 0.56 g with a calculated overall yield of 88 percent and has a melting point of 197° to 199° C.
