Abstract:
Thiofluorescein was synthesized in a preparative yield by successive demethylation of 3,3'-dimethoxydiphenyl sulfide to 3,3'-dihydroxydiphenyl sulfide and condensation of the latter with phthalic anhydride in H2SO4. The title compound was also obtained in a higher yield from 3,3'-dimethoxydiphenyl sulfide directly in a one-pot process combining the condensation in H2SO4 and demethylation in 2Py center dot H2SO4.
