The desulfurization of thioacetals and thioethers by a pyridine-derived electron donor is described. This methodology provides efficient access to the reduced products in high yields and does not require the use of transition-metals, elemental alkali-metals, or hydrogen atom donors.

The electrosynthesis of hypervalent iodobenzene difluorides was accomplished by anodic oxidation of p-nitro- and p-methoxyiodobenzenes with Et(3)N.3HF in anhydrous acetonitrile, and p-methoxyiodobenzene difluoride was used as a mediator for indirect anodic gem-difluorination of dithioketals.
