Front Cover: PdBr2‐Catalyzed Acetal Formation of Carbonyl Compounds Using Diazophenanthrenequinone: Utility of 9, 10‐Phenanthrenedioxyacetal (Eur. J. Org. Chem. 33/2020). Issue 33 (27th August 2020) - Kitamura, Mitsuru
Abstract : The Front Cover shows the new acetalization method of ketones and aldehydes under non‐acidic conditions using diazophenanthrenequinone and PdBr2 . The formed acetals, that have a phenanthrene skeleton, withstand under mild acidic conditions. Removal of acetals was successfully proceeded under oxidation conditions or strong acidic conditions. We thank our university, Kyushu Institute of Technology, the background colors, polka dots, dark gray and vermilion, are based on the flag of our university.
