Abstract
Expression of concern for ‘SO2F2-Mediated one-pot cascade process for transformation of aldehydes (RCHO) to cyanamides (RNHCN)’ by Yiyong Zhao et al., RSC Adv., 2020, 10, 17288–17292, DOI: https://doi.org/10.1039/D0RA02631J.
RSC Advances is publishing this Expression of Concern in order to alert our readers to the fact that we are presently unable to confirm the accuracy of the information published in this article related to compound 2w. A reader has raised concerns that the 13C NMR spectrum provided for compound 2w does not fit the reported structure. The authors disagree with the reader's claims. An independent expert has reviewed the matter and has recommended that the authors must provide further evidence, from X-ray or other confirmatory tool, in order to prove the proposed structure of compound 2w.
An expression of concern will continue to be associated with this article until a conclusive outcome is reached.
