Ruthenium-Catalyzed Allylic Substitution of Allylic Cyclic Carbonates

Abstract
Allylic substitution of allylic cyclic carbonates with PhSH or PhOH in the presence of CpRu(PPh3)2Cl (5 mol %) afforded (E)-allylic alcohol and erythro-β-hydroxy thiophenoxide or phenoxide respectively, via external attack of nucleophiles to π-allyl ruthenium complex.
