ABSTRACT:
A method for making diarylthioethers including thioetherbis(phthalic anhydrides) and thioetherbis(phthalimides) in the absence of a solvent medium by the interaction of sulfide compounds, including alkali metal sulfides and alkali metal hydrogen sulfides, with molten organo-substituted aromatic compounds including phthalic anhydrides and phthalimides mediated by a phase transfer catalyst.
