An Expedient Synthesis of Alkynyl Trifluoromethyl Sulfones

Abstract
The hitherto difficultly attainable alkynyl trifluoromethyl sulfones 7 were prepared by the reaction of alkynyl sodium salts 6 with trifluoromethanesulfonic anhydride (1) in modest to good yields. The reactivity of 7 with different nucleophiles was studied.
