Symmetrical ditocopheryl disulfides (Toc)(2)S-2 and symmetrical and unsymmetrical ditocopheryl sulfides (Toc)(2)S were simply prepared under remarkably mild conditions with complete control of the regiochemistry by using delta-, gamma-, and beta-tocopheryl-N-thiophthalimides (Toc-NSPht) as common starting materials. The roles of sulfur atom(s), H-bond and aryl ring substitution pattern on the antioxidant profile of these new compounds, which were assembled by linking together two tocopheryl units, are also discussed.

Abstract
Symmetrical ditocopheryl disulfides (Toc)(2)S-2 and symmetrical and unsymmetrical ditocopheryl sulfides (Toc)(2)S were simply prepared under remarkably mild conditions with complete control of the regiochemistry by using delta-, gamma-, and beta-tocopheryl-N-thiophthalimides (Toc-NSPht) as common starting materials. The roles of sulfur atom(s), H-bond and aryl ring substitution pattern on the antioxidant profile of these new compounds, which were assembled by linking together two tocopheryl units, are also discussed.File in questo prodotto:
