Palladium(0)-catalyzed alkylation of thiols

Palladium(0)-catalyzed alkylation of various allylic carbonates by aromatic thiols allowed the easy preparation of various allylic aryl sulphides in quite good yields. The reaction was regioselective with substitution at the less hindered side of the π-allyl system whatever the temperature of the reaction, and was diastereoselective with net retention of configuration.
Palladium-catalyzed allylation of pyrimidine-2,4-diones (uracils) and of 6-membered heterocyclic ambident sulfur nucleophiles
Moreno-Manas,Pleixats,Villarroya
, p. 1457 - 1464 (2007/10/02)
Pd(O)-Catalyzed allylation of six-membered ambident heterocycles bearing NH-CO, NH-CS and CH2-CO moieties obey the regioselectivity rules: C>O; N>O; S>N; NH-CO>NH-CS. Uracil and 5-methyluracil (thymine) do not show regioselectivity (N-1 = N-3) whereas 6-methyluracil is regioselectively allylated at N-3 (N-3>N-1).
A NEW SYNTHESIS OF 1,3-DIENES FROM ALLYL SULFIDES AND ALLYL SULFONES USING TRI-n-BUTYLSTANNYLMETHYL IODIDE

Allyl 2-pyridyl sulfide 6 or allyl phenyl sulfone 7 on treatment with n-butyllithium in tetrahydrofuran followed by tri-n-butylstannylmethyl iodide (4) afforded directly the 1,3-diene 8 in good yield.
