•Oxygen-atom was definitely transferred from the carbonyl group of DMF.•New transformation of NHC–Cu complexes into imidazolinones.•Trifluoromethyl species has vital effect for this reaction.
An unprecedented protocol for oxygen-atom insertion reaction of NHC–copper complexes has been developed by employing N,N-dimethylformamide as the oxygen source, which allows the preparation of imidazolinones from carbene complexes and decodes one of the mysterious transformations of NHC–metal complexes as well.
Graphical abstractA novel oxygen-atom insertion of NHC–copper complexes has been described using N,N-dimethylformamide as the oxygen source. It allows the preparation of various imidazolinones (3a–d) in up to 99% yield.Figure optionsDownload full-size imageDownload as PowerPoint slide
