Abstract

Reaction of l, l-dichloro-2, 2-dicyanoethylene with 4 equiv of argentous fluoride provides the silver salt of trifluoromethylmalononitrile, which can be converted to trifluoromethylmalononitrile by treatment with hydrogen chloride. Under the same conditions, reaction of the chloro cyano olefin with 2 equiv of argentous fluoride provides solutions from which the yellow dye l-fluoro-l-(4-dimethylaminophenyl)-2, 2-dicyanoethylene can be ...
