Diallylic polysulfides (polysulfanes) are provided with sulfur chain lengths of 9 to 22. Also provided are bis(2-methyl-2-propenyl) polysulfides with sulfur chain lengths of 3 to 22. Also provided are 2-substituted bis(2-propenyl) polysulfides with sulfur chain lengths of 3 to 20. Also provided are the 2-cycloalken-1-yl polysulfides, 2-cyclohexen-1-yl polysulfides and 2-cyclopenten-1-yl polysulfides, with sulfur chain lengths of 3 to 20. Also provided are processes for extending the sulfur chain length of diallylic polysulfides and 2-substituted analogues thereof and allyl methyl polysulfides by bringing such compounds into contact with elemental sulfur and heating, or by mixing with molten sulfur. |
