Palladium(0)-catalyzed alkylation of various allylic carbonates by aro
matic thiols allowed the easy preparation of various allylic aryl sulp
hides in quite good yields. The reaction was regioselective with subst
itution at the less hindered side of the pi-allyl system whatever the
temperature of the reaction, and was diastereoselective with net reten
tion of configuration.
