The combination of Mo and cationic Au catalysts dramatically accelerated the rearrangement of diverse propargyl alcohols to yield α,β-unsaturated compounds under mild conditions, and high product yields. A practical application to the highly challenging primary propargyl alcohols and the N-alkynyl amides is achieved.
