A combination of IPrAuNTf(2) as catalyst in the presence of Selectfluor has been successfully used for the high yielding synthesis of alpha-fluoroenones via 1,3-acyloxy rearrangement of propargyl acetates followed by Csp(2)-F bond formation, likely involving a redox Au(I)/Au(III) catalytic cycle.

A highly efficient gold-catalyzed oxidative dimerization of propargylic acetates is developed. In this chemistry, Selectfluor oxidation of Au(I) to Au(III) is readily incorporated into Au-catalyzed tandem reactions of propargylic acetates, and transmetallation and reductive elimination on Au(III) intermediates are likely involved.
