Abstract
This work describes a comprehensive study on the reactivity of organotins with elemental sulfur for producing organosulfur compounds and Ar-S bonds. Elemental sulfur, fluoride ions and organotins reacted under aqueous, aerobic and almost neutral conditions to selectively generate disulfides, without forming thiols or thioethers (or sometimes trisulfides). Several parameters were examined in depth: organotins, carbon ligands, fluoride sources, temperatures, solvents and equivalents of sulfur.
Key words
sulfur - organotins - fluoride ions - hypercoordination - aryl disulfides
