Corrigendum: Direct Allylation of In Situ Generated Aldehyde Acyl Anions by Synergistic NHC and Palladium Catalysis.

Abstract

The authors of this Communication have been alerted regarding a structural assignment mistake. A double-check of the data revealed that the major isolated products were allyl esters and not the expected allyl ketones (see scheme). 1 Plausibly the formed acyl anions were oxidized under the reaction conditions to the corresponding carboxylates, leading to the esters as the major product. The presence of an additional oxygen atom in the product was not realized, probably because the analytical (HRMS: The observed M+K was actually M (for ester)+Na) and spectral data (close δ values in 1H and 13C NMR spectra) were misinterpreted and initially compared with data for a wrong known compound. Apart from this wrong structural assignment, all yields, data, copies of spectra, and the experimental sections reported in the manuscript and the supporting information remain valid. The authors wish to thank Professor T. Rovis and Professor R. Lundgren for bringing this matter to their attention. They sincerely apologize to the scientific community for this severe inadvertent mistake.
