Retraction: Nanoporous Au/Ag Catalyzed Benzylic sp3C−H Oxidation of 9H-Fluorene Derivatives and Similar Molecules With TBHP

RETRACTION: J. Thayssen, W. Riedel, T. Risse, A. Staubitz and A. Wittstock, “Nanoporous Au/Ag Catalyzed Benzylic sp³C−H Oxidation of 9H-Fluorene Derivatives and Similar Molecules With TBHP,” ChemCatChem 2024, 16, e202301695, https://doi.org/10.1002/cctc.202301695.

The above article, published online on 25 March 2024 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal Editor-in-Chief, Sandra González Gallardo; and Wiley-VCH GmbH, Weinheim. Following publication, the authors noticed that for some experiments, there might have been cross-contamination with another catalyst due to an insufficient cleaning procedure by laboratory dish washer only. As it is unclear which experiments are affected, all need to be reproduced. The authors intend to repeat experiments to produce correct data. Since repetition of experiments will take considerable time and the editors cannot be certain that new data will not affect the conclusions of the study, they have decided it is appropriate to retract the article.
