The preparation of new bis[(diphenylphosphinoyl)methyl] sulfides, selenides, and tellurides is described by the reaction of (diphenylphosphinoyl) methyl p-toluenesulfonate with sodium chalcogenides. The title compounds are subjected to Horner-Wittig-type

Copper(I) salt promoted reaction of vinyl bromides with dibenzoyl disulfide in hot aprotic polar solvent produced thiophene derivatives in moderate yields, while the corresponding reaction with sodium thiobenzoate led to S-vinyl thiobenzoates in good yields.
A Direct Formation of Alkenyl Chalcogenides from Nonactivated Alkenyl Halides and Diorganyl Dichalcogenides under Neutral Conditions
Ogawa, Takuji,Hayami, Kazuo,Suzuki, Hitomi
, p. 769 - 772 (2007/10/02)
Alkenyl sulfides and selenides were easily obtained in moderate to good yields by heating the corresponding bromides with diorganyl disulfides or diselenides in hexamethylphosphoric triamide with or without copper(I) iodide as a promoter.

Aromatic thiols and 2-thiophenethiol react with β-chloro- and β-bromostyrene when heated to form the corresponding 1-phenyl-2-aryl(thienyl)thioethenes.The reaction begins at 80 deg C and takes place effectively and strictly stereospecifically at 140-160 deg C.The yield of the respective vinyl sulfides amounts to 70-95percent. β-Bromostyrene reacts with thiophenol more slowly than β-chlorostyrene,and this is due to the inhibiting action of the hydrogen bromide, which acts as a trap for the thiyl radicals and gives rise to decomposition of the obtained 1-phenyl-2-phenylthioethene.A mong the investigated thiols 2-thiophenethiol has the lowest reactivity.
