Abstract
The presence of a base strongly improves the efficiency and the selectivity of the Pd-catalyzed oxidation of terminal alkenes in carboxylic acids. The methodology is particularly well adapted for the oxidation of homoallylic alcohols, for which the resulting acyloxylated products are obtained selectively as E-isomers in good yields.
