On the PdCl2-catalyzed synthesis of allylic azides and allylic sulfonamides from homoallylic alcohols

According to experimental and literature data, the one-pot formation of allylic azides or sulfonamides from catalytic amounts of PdCl2, homoallylic alcohols and TMSN3 or TsNH2 occurs through CC migration followed by regioselective nucleophilic addition on the PdII-activated CC bond and β-OH elimination.
