Trifluoromethanesulfonic acid catalyzed isomerization of kinetic enol derivatives to the thermodynamically favored isomers was developed. Under the present conditions, kinetic enol phosphates, enol acetates and benzoates, and enol sulfonates were smoothly isomerized to produce the corresponding thermodynamically favored isomers in good to excellent yields.

(Chemical Equation Presented) Gold, gold, or... gold? It depends on the (gold) catalyst whether the product of thermodynamic or kinetic control is formed in an unprecedented hydrophosphoryloxylation approach to enol phosphates (see scheme). A third catalyst, [(C6F5) 3PAuOTf], was found to be exceedingly effective for the previously unknown isomerization of kinetic enol phosphates to the thermodynamically favored isomers.
