(Figure presented) With an [Ir(COD)Cl]2/phosphoramidite ligand system, an allylic substitution of O-allyl carbamothioates was developed. The reaction proceeded in the favor of branched products with up to 93:7 branched-to-linear ratio, affording chiral S-allyl carbamothioates with up to 95% ee.

The fractional distillation of O-(2-alkenyl or 2-cycloalkenyl) S-alkyl dithiocarbonates (xanthates) affords 2-alkenyl or 2-cycloalkenyl alkyl sulfides.The reaction involves the -sigmatropic rearrangement of the xanthates to produce S-(2-alkenyl or 2-cycloalkenyl) S-alkyl dithiocarbonates followed by extrusion of carbon oxysulfide to give 2-alkenyl or 2-cycloalkenyl alkyl sulfides.
