Abstract
Chloro-6'-diethylaminofluoran and 2'-chloro-3'-methyl-6'-diethylaminofluoran were reacted with various diphenols in dimethyl formamide in the presence of potassium car- bonate to give the related bis-fluoran compounds. All the synthesized derivatives were identi- fied by conventional methods (IR, 1 H-NMR), elemental analysis and UV-visible spectroscopy in organic solvent and 95 % acetic acid. All the fluoran compounds change their colour in acidic media.
