Chromium(III) and indium(III) 3,6-di-tert-butyl-o-semiquinolate complexes as redox mediators of hydrogen sulfide oxidation in reactions with cycloalkanes

The electrochemical oxidation of the chromium(III) and indium(III) complexes with 3,6-di-tert-butyl-o-semiquinolate leading to the formation of active monocationic species is studied by cyclic voltammetry. The reactions of the latter with hydrogen sulfide generate the radical cation of H2S, whose fragmentation affords the proton and thiyl radical. These complexes are proposed for the first time as redox mediators for the one-pot thiolation of inert cycloalkanes C6–C8, which decreases the activation energy of hydrogen sulfide compared to that for direct electrochemical oxidation. The major products of cycloalkane functionalization involving H2S are thiols and organic di- and trisulfides. The yield of the synthesized compounds depends on the type of the mediator: the chromium(III) complex exhibits the highest efficiency in the electrocatalytic transformations.

3,4-Dichloro-1,2,5-thiadiazole: a commercially available electrophilic sulfur transfer agent and safe resource of ethanedinitrile

3,4-Dichloro-1,2,5-thiadiazole is introduced as a safe and efficient sulfur transfer reagent. By applying this commercially available reagent, the symmetrical trisulfides and ethanedinitrile were simultaneously obtained by reacting various thiols with this reagent at room temperature. This reagent is non-toxic, inexpensive, and commercially available. In addition, no higher-order polysulfides were detected in all cases after the completion of the reaction. The short reaction times (20–50 min), excellent selectivity, and high yield of the trisulfides are some attractive merits of this reagent for the preparation of trisulfides. The reaction is one-pot, and isolation-purification of intermediates is not required. The procedure was readily scaled up to 5 grams. A mechanism is presented to explain the chemistry.
