Abstract

Cyclic disulfide macrocycles were rapidly synthesized cleanly and selectively from rigid dithiols via oxidation with iodine when activated by pnictogen additives (As and Sb). Macrocycles were confirmed by (1)H-NMR spectroscopy and X-ray crystallography. A p-xylyl-based disulfide trimer and tetramer crystallized in hollow, stacked columns stabilized by intermolecular, sulfur···sulfur close contacts.
