The cobalt-catalyzed carboxylation of propargyl acetates with CO2 (1 atm) is described. The reaction proceeds at room temperature in the presence of Mn powder as a reducing reagent. Various propargyl acetates are converted to the corresponding carboxylic acids in good to high yields.

Gold-catalyzed intermolecular oxidation of carboxylates of primary or secondary propargylic alcohols are realized with excellent regioselectivity, which is ascribed to inductive polarization of the C-C triple bond by the electron-withdrawing carboxy group

experimental part, p. 1846 - 1855 (2009/07/04)
Versatile linear α-iodo- and α-bromoenones are prepared efficiently from readily accessible propargylic acetates using 2 mol % of Au(PPh3)NTf2. This reaction is easy to execute and has broad substrate scope. Good to excellent Z-selectivities are observed in the cases of propargylic acetates derived from aliphatic aldehydes.

, p. 2147 - 2150 (2008/02/03)
Only 2 mol % of Au(PPh3)NTf2 is needed to convert readily accessible propargylic acetates into versatile linear α-iodoenones in good to excellent yields. This reaction is easy to execute and has broad substrate scope. Good to excellent Z-selectivities are observed in the cases of aliphatic propargylic acetates derived from aldehydes.
