    • While the term "chiral dichalcogenide" has sometimes been used, the chiralities of most of those compounds have been due to the substituents on the chalcogen atoms, see: (a) Wirth, T. Tetrahedron 1999, 55, 1.

    • Typical procedure for chiral crystallization of diphenyl dichalcogenides: ca. 1.0 g of diphenyl disulfide or diphenyl diselenide, which was preliminary purified by silica gel column chromatography and then recrystallization. was dissolved in refluxing ethanol (ca. 15 or 40 mL, respectively), and the solution was cooled slowly to room temperature. Precipitated crystals were collected by suction filtration to give chiral crystals of the disulfide (32-74%) or diselenide (16-73%). Similarly, 0.6 g of diphenyl ditelluride was recrystallized from hot petroleum ether (ca. 45 mL) to yield chiral crystals of the ditelluride (57-84%).

    • A mixture of a single crystal (ca. 2 ing) of the dichalcogenide and 100 mg of KBr was ground and formed into disk with a radius of 6.5 mm.

    • Theoretical study: Geometries, vibrational frequencies, and energies were calculated by using Density Functional Theory (B3LYP). The double-ζ plus polarization basis set of hydrogen, carbon, and sulfur atoms was used. The (5s 4p 2d/12s 8p 5d) and (10s 8p 4d/16s 11p 6d) basis sets were also used for the selenium and tellurium atoms, respectively.
