A new method to synthesize α-fluoroacetals and α-fluoroketones is presented here. In the presence of alcohols and Selectfluor, catalytic amounts of gold selectively transformed alkynes into the corresponding fluorinated acetals or ketones depending on the reaction conditions. This protocol has been applied to both terminal and internal alkynes showing a high degree of chemo- and regioselectivity
