文摘
The use of a copper鈥搃ron mixed oxide as a heterogeneous catalyst for the efficient synthesis of 伪-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.
