Taking the air! A PdII‐catalyzed intramolecular hydroamination of allenes coupled to alcohol oxidation has been developed. This reaction is performed by using a nitrogen‐based ligand under aerobic conditions, under which the molecular oxygen is used as the terminal oxidant for the reoxidation of Pd0 species to complete the catalyticcycle.

Allylic phenyl and methyl sulfides bearing a strategically positioned electrophilic center have been shown to undergo concomitant [2,3]-sigmatropic rearrangement and intramolecular N-alkylation upon oxidative conversion to allylic sulfilimines and treatment with aqueous base. This one-pot transformation leads to the title class of compounds in good yield.
