Au(I)-catalyzed hydroacyloxylation of alkynes with carboxylic acids is described PPh3AuCl/AgPF6 catalyst affords the Markonikov addition products, whereas PPh3AuCl/AgOTf catalyst gives the more stable isomerized products via the Markonikov products
Selective <i>O</i>‐Acylation of Enol Silyl Ethers with Acyl Fluorides Catalyzed by Fluoride Ions Derived from Potassium Fluoride and 18‐Crown‐6
Fluoride ions derived from potassium fluoride and 18-crown-6 efficiently catalyzed the selective O-acylation of a variety of enol silyl ethers with aromatic and aliphatic acyl fluorides to produce unique enol ester derivatives.
