SYNTHESIS OF CYCLIC TRISULFIDES BY USING SILYL AND TIN SULFIDES

Sulfur dichloride was allowed to react with linear and cyclic, silyl and tin sulfides prepared from alkanedithiols.Of the sulfides, bis(trimethylsilyl) sulfides were most effective for synthesis of cyclic trisulfides.

The Utilization of Titanocene Polysulfide complexes for the Synthesis of Organic Polysulfanes

Titanocene pentasulfide reacts with Ph3CCl and CCl3SCl to give (Ph3C)2S5 and (CCl3)2S7, respectively, the molecular structures of which show helical CSnC backbones. (Ph3C)2S6 and (CN)2S9 possess non-helical structures. C2H4(SCl)2, C6H4(SCl)2, C6H4(SSCl)2 and CH3C6H3(SCl)2 react with Cp2TiS5 to give the corresponding sulfur-rich heterocycles with up to nine sulfur atoms. Dicyclopentadiene trisulfane is used to prepare the dicyclopentadiene tetra-, penta-, hexa- and octasulfanes by (a) derivatization to SCl or SH compounds followed by sulfur transfer reactions using Cp2TiS5, (Cp'2ClTi)2S3 or S2Cl2 as reagents. Several cyclic, bicyclic and tricyclic organosulfur heterocycles are obtained from Cp4Ti2C2S4 or from Cp2TiS2C3H6 by reactions with SCl2, S2Cl2, C2H4(SCl)2, COCl2 or C6H4(SCl)2.

NEW SULFUR CONTAINING TITANACYCLES

Titanocenedicarbonyl, Cp2Ti(CO)2, activates the sulfur-sulfur bond in organic disulfides and sulfur homocycles like S6, S7 and S8.Cyclic disulfides form chelating ligands with sulfur atoms attached to the Ti atom.The reaction with S6 yields a new compound with an eight sulfur atoms containing ligand.The novel titanocene compounds have been used as precursors for the synthesis of a series of methylene polysulfides.

Synthesis of Cyclic Polysulfides. Reactions of Dithiols and Related Compounds with Elemental Sulfur in Liquid Ammonia

Many cyclic polysulfides, i.e., benzopentathiepins (3a-d), 6H-1,2,3,4,5-benzopentathiocin, 5H-1,2,3,4-benzotetrathiepin, 3H-1,2-benzodithiole, 1,5-dihydro-2,3,4-benzotrithiepin, 1,4-dihydro-2,3-benzodithiin, naphtho-1,2-dithiole, 1,2,3-trithiane, 1,2-dithiane, 2,3,4,5-tetrathiabicyclodecane, and 2,3,4,5,6-pentathiabicycloundecane, were synthesized in high yields by new reactions of their corresponding dithiols and related compounds, 1,3-benzodithiole-2-thiones (5) and 1,3-dithiolane-2-thione, with elemental sulfur in liquid ammonia at ambient temperature.In the synthesis of 3a-d from 1,2-benzenedithiol or 5, considerable increase in the product yield was observed upon adding 1,3-dinitrobenzene to the solvent used in work-up.
