Regioselective C-H Thioarylation of Electron-Rich Arenes by Iron(III) Triflimide Catalysis
Dodds, Amy C.,Sutherland, Andrew
, p. 5922 - 5932 (2021/05/04)
A mild and regioselective method for the preparation of unsymmetrical biaryl sulfides using iron(III) catalysis is described. Activation of N-(arylthio)succinimides using the powerful Lewis acid iron(III) triflimide allowed the efficient thiolation of a range of arenes, including anisoles, phenols, acetanilides, and N-heterocycles. The method was applicable for the late-stage thiolation of tyrosine and tryptophan derivatives and was used as the key step for the synthesis of pharmaceutically relevant biaryl sulfur-containing compounds such as the antibiotic dapsone and the antidepressant vortioxetine. Kinetic studies revealed that while N-(arylthio)succinimides bearing electron-deficient arenes underwent thioarylation catalyzed entirely by iron(III) triflimide, N-(arylthio)succinimides with electron-rich arenes displayed an autocatalytic mechanism promoted by the Lewis basic product.

A procedure has been developed for the synthesis of bis(2- arylcarbonylamino-1H-benzimidazol-5-yl) sulfones by reaction of the corresponding substituted benzoyl chloride with sodium cyanamide and subsequent treatment of the N-cyanobenzamide thus formed with 3,3′,4,4′- tetraaminodiphenyl sulfone in acid medium. The products were tested for fungicidal activity.
