An efficient aerobic linear allylic C-H amination under palladium(II)/bis-sulfoxide/Brønsted base catalysis operates under operationally simple conditions (1 equiv of olefin, 1 atm O2 or air) with reduced catalyst loadings while providing higher turnovers and product yields than systems employing stoichiometric benzoquinone (BQ) as the terminal oxidant.
