Acyloxylation of 1,4-Dioxanes and 1,4-Dithianes Catalyzed by a Copper-Iron Mixed Oxide.

摘要: The use of a copper–iron mixed oxide as heterogeneous catalyst for the efficient synthesis α-acyloxy-1,4-dioxanes and 1,4-dithianes employing t-butyl peroxyesters is reported. preparation characterization are described. effect heteroatoms plausible mechanism discussed. method operationally simple involves low-cost starting materials affording products in good to excellent yields.
