A Highly Regioselective Palladium‐Catalyzed O,S Rearrangement of Cyclic Thiocarbonates

This work describes an operationally simple catalytic synthesis of cyclic S ‐thiocarbonates with predictable regioselectivity in good yields. The reaction utilizes substrates derived from ubiquitous 1,2‐diols in an atom economical intramolecular rearrangement, catalysed by an inexpensive and simple catalyst–ligand system. A crystal structure is presented that clearly confirms the regioselectivity of the reaction.
