Abstract
A SO2F2-promoted dehydration and dehydrogenation of abundant alcohols enables a direct synthesis of alkynes in high yields under mild conditions. This straightforward transformation requires only inexpensive and readily available reagents. The crude alkynes are sufficiently free of impurities to permit direct use in Cu-catalyzed alkyne-azide cycloaddition reactions with PhN3 and Sonogashira couplings.
