Procedure

A solution of sodium dithionite (8.00, 0.0460 mole) and sodium carbonate (7.01 g, 0.0661 mole) in water (50 ml) was stirred under a nitrogen atmosphere while 2,2'-bis(phenylethynyl)-5,5'-dinitrobiphenyl (0.500 g, 0.00112 mole) was added followed by dioxane (50 ml). The reaction mixture was stirred and refluxed for 2 hours and then the solvent was removed under vacuum. The residue was extracted with benzene and the filtered benzene extracts were freeze-dried to afford 0.198 g (46%) of 2,2'-bis(phenylethynyl)-5,5'-diaminobiphenyl, m.p. 159°-161° C. after recrystallization from chloroform-cyclohexane.
