Participants

Reaction Steps

Diaminomaleonitrile (4.4 g, 0.04 mol) was dissolved in methanol (100 ml) and 2,6-dichloro-4-trifluoromethylbenzaldehyde (9.6 g, 0.04 mol) was added with stirring at ambient temperature. The reaction mixture was stirred for 30 minutes and heated at reflux for 1 hour. After cooling to 10° C. a solid which had separated was filtered off co give 1-amino-2-(2,6-dichloro-4-trifluoromethylbenzylideneamino)-1,2-dicyanoethylene (10.3 g) as a yellow crystalline solid, m.p. 218°-219° C.
