Dyes produced by the reaction of 1,2,3,4-tetrafluoro-9,10-anthraquinones with bifunctional nucleophiles

1,2,3,4-Tetrafluoro-9,10-anthraquinones reacted with a molar amount of bifunctional nucleophiles, such as 2-aminophenol, catechol, 2-aminobenzenethiol, ethylenediamine, and 1,4-butanediamine to produce the 1,2-cyclized products, which further reacted with another molar amount of bifunctional nucleophiles to afford the dicyclized derivatives.
