Investigation of sulfur extrusion from a cyclic dialkoxy disulfide

[GRAPHICS] The relationship of cyclic dialkoxy disulfide 11, its thionosulfite isomer 12, and the related sulfoxylate 13 has been examined. Investigations demonstrate an interconversion between thionosulfite 12 and sulfoxylate 13. This sequential transformation brings evidence that a branched-bond sulfur structure is likely involved in sulfur extrusion.
