Color Change of (E)-2,3-Bis(2,3,4,5,6-Pentafluorophenyl)-3-acrylonitrile by the Addition of Amines

(E)-2,3-Bis(2,3,4,5,6-pentafluorophenyl)-3-acrylonitrile (3E) was synthesized.A benzene solution of 3E turns into a brillant red color by the addition of aliphatic amines.The coloration mechanism is studied by optical absorption, conductivity and product analyses.It has become apparent that ion-pair formations between 3E and the amines by proton transfer reactions are responsible for the coloration.Structural requirements of the amines for the ion-pair formation are discussed.
