Several examples of (α-perfluoroheptyl-β,β-dicyanovinyl)aminostyrenes (3), a novel class of perfluorocarbon-soluble dyes, were prepared by the reaction of 2-chloro-1,1-dicyano-2-(perfluoroheptyl)ethylene (2) with aromatic amines.The ethylene 2 was prepared from methyl perfluorooctanoate, malononitrile, and phosphorous pentachloride.The λmax for perfluorohexane solutions of the dyes ranges from 419 nm for the dye prepared from N-phenylmorpholine to 490 nm for the dye prepared from julolidine.

The synthesis of 1,1-dicyano-2-chloro-2-trifluoromethylethylene was realized.Its reaction with nucleophilic reagents (alcohols, amines, 1,3,3-trimethyl-2-methyleneindoline, and dimethylaniline) leads to products from substitution of the chlorine atom.For 1,1-dicyano-2-(p-dimethylaminophenyl)ethylenes with various substituents at position 2 a correlation was obtained between the absorption frequency in the electronic spectrum and the ?I and ?R constants of the substituents.
