4,4′-diarylsulfanyl-2,2′,5,5′-tetraoxybiaryl derivatives as a water-soluble fluorescent dye

4,4′-Disulfanyl-2,2′,5,5′-tetrahydrobiaryl (5,5′-disulfanyl hydroquinone dimer) derivatives were readily synthesized from benzoquinone and thiols via an oxidative coupling reaction. The hydroquinone dimers showed strong fluorescence upon excitation at 330

Facile synthesis of quinone dimer derivatives substituted with sulfanyl groups and their properties

Quinone dimers are readily prepared quantitatively from 2- sulfanyl-1,4-dimethoxybenzene by oxidative treatment. The oxidative coupling progressed in a highly regioselective manner. Removal of O-protection and subsequent oxidation gave 5,5'- bis(sulfanylquinone) dimer in good yields. Physical properties of the dimer derivatives are also investigated.
