Abstract
A general synthetic route was used to prepare 15 new N-heterocyclic carbene (NHC) silver(I) complexes bearing anionic carboxylate ligands, [Ag(NHC)(O2CR)], including a homologous series of complexes of sterically flexible ITent ligands, permitting a systematic spectroscopic and theoretical study of the structural and electronic structures of these compounds. The complexes displayed significant ligand accelerated effect in the intramolecular cyclisation of propargylic amides to oxazolidines. The substrate scope is highly complementary to that achieved previously by NHC-Au and pyridyl-silver(I) complexes.
