The combination of Mg2+ and PF6- as counteranion catalyzes a transition-metal-free dehydrative cross-coupling of unactivated primary/secondary alcohols with amines/amides under environmentally benign conditions. A wide range of allylic alcohols and amines/amides were tolerated well in this efficient transformation.
