(α-PERFLUOROHEPTYL-β,β-DICYANOVINYL)AMINOSTYRENES: A NOVEL CLASS OF PERFLUOROCARBON-SOLUBLE DYES

Freed, Bethany K.,Middleton, W. J.

, p. 219 - 225 (2007/10/02)

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.
