A1 Ortega Agüera, María Jesús A1 Gatica Casas, José Manuel A1 Martínez Massanet, Guillermo A2 Química Orgánica K1 Acyloxylation AB The use of a copper−iron mixed oxide as a heterogeneous catalyst for the efficient synthesis of α-acyloxy-1,4-dioxanes and 1,4-dithianes employing t-butyl peroxyesters is reported. The preparation and characterization of the catalyst are described. The effect of the heteroatoms and a plausible mechanism are discussed. The method is operationally simple and involves low-cost starting materials affording products in good to excellent yields.
