Several reaction systems have been investigated as possible sources of diatomic sulfur (S$ sb2$). Dialkoxy disulfides have been shown to thermally decompose with the formation of sulfur likely as S$ sb2$ which was successfully trapped in modest yield. Several other systems have been shown to decompose with a likely S$ sb2$ intermediate. / The chemistry of the chloro(triphenylmethyl)sulfides was studied. The X-ray crystal structures of the first chlorodisulfide and chlorotrisulfide were obtained. The chlorotriphenylmethyl sulfides were found to decompose in the presence of 1,3-dienes to yield products which are consistent with the trapping of diatomic sulfur. The reactions of the chloro(triphenylmethyl)sulfides were examined and used to prepare a series of mixed sulfides containing 1-4 sulfurs. A novel extrusion of sulfur in the reaction of chloro(triphenylmethyl)monosulfide with thiocarbonyl compounds was investigated. The thermal decomposition of the sulfides as solids and in solution were examined. / The solvent dependent desulfurization of sulfenic sulfonic thioanhydrides was investigated in the anticipation of discovering a diatomic sulfur intermediate. The extrusion was shown to involve the concatenation of sulfur atoms until a stable sulfur ring could be extruded. / The X-ray crystal structure of bis(triphenylmethyl)disulfide was determined and was discussed in relation to other hindered disulfides.
