Retraction: An efficient one pot three-component synthesis of 2,4,6-triarylpyridines using triflimide as a metal-free catalyst under solvent-free conditions

摘要

The Royal Society of Chemistry hereby wholly retracts this RSC Advances article. The NMR spectra for compounds 3a–3k and 3s–3uin the ESI have been reproduced without permission from a Tetrahedron Letters paper by Fei Ling et al. 1 The authors stated that astheir 2,4,6-triarylpyridines products are known, they only characterised three of their compounds using1 H NMR and 13 C NMR,which were identical to those reported in the literature. Therefore, the authors do not have full characterisation data for theirpublished paper.
