Abstract
Electrolysis of organic disulfides in liquid sulfur dioxide is used to obtain organothiating agents, which can then be reacted with appropriate substrates to effect the synthesis of organothioaromatic compounds efficiently and in high yields. With appropriate phenolic compounds, regioselective substitution occurs in which para substitution greatly exceeds ortho substitution.
Claims19
A process which comprises generating an organothiating agent from an organic disulfide in which the organic groups are (i) primary or secondary organic groups and are (ii) free of nonaromatic unsaturation, via electrolysis in liquid sulfur dioxide.
A process which comprises:
- A) generating an organothiating agent solution from an organic disulfide in which the organic groups are (i) primary or secondary organic groups and are (ii) free of nonaromatic unsaturation via electrolysis in liquid sulfur dioxide;
- and
- B) contacting at least a portion of the solution from said electrolysis with an organothiatable aromatic compound in order to organothiate the aromatic compound.
